The control of 0 is performed. The disc recording / reproducing unit 30 is a digital audio signal recording / reproducing system using the above-mentioned mini disc.

The structure of the disc recording / reproducing unit 30 is shown in FIG. 2. Reference numeral 31 in the figure denotes a disc cartridge in which a disc is accommodated, and a magneto-optical disc 32 having a diameter of 64 mm is accommodated in the cartridge 31. . In this case, the disc 32 is housed in the cartridge 31 while being mounted in the recording / reproducing apparatus, and is rotationally driven by the spindle motor 33. Then, the optical pickup 34 reads a recording signal recorded by magnetic field modulation, which will be described later, on a track formed in a spiral shape or a concentric shape on the disk 32, and a reproduction signal is supplied to a modulation / demodulation processing circuit 36 via an RF amplifier 35. The supplied data is demodulated for the data modulated for recording. As the recording modulation and demodulation processing in the modulation / demodulation processing circuit 36, for example, 8-14 modulation (EFM) is used.
A digital modulation referred to as is performed. Also, this modulation
The processing in the demodulation processing circuit 36 is performed under the control of the disk control unit 12.

Address data is previously recorded on each track formed on the magneto-optical disk 31 by wobbling (meandering), and the address decoder 39 detects this wobbling information. That is, R
The reproduction signal output from the F amplifier 35 is applied to the address decoder 3
9, the decoder 39 decodes the address data recorded by wobbling, and supplies the decoded address data to the disk controller 12 via the modulation / demodulation processing circuit 36.

The audio data demodulated by the modulation / demodulation processing circuit 36 is supplied to the memory controller 40,
The RAM 41 connected to the memory controller 40 is temporarily stored. The RAM 41 is a data buffer for continuously outputting the audio data even when the reproduced data is temporarily interrupted, and supplies the data stored in the RAM 41 to the compression / expansion processing circuit 42. Then, the data compressed for recording by the compression / expansion processing circuit 42 is expanded to the original data amount, and this expanded data is converted into an analog signal by the digital / analog converter 43,
This analog signal is supplied to the reproduction signal output terminal 44.

Further, the optical pickup 34 and the recording head 48, which will be described later, are moved in the radial direction of the disk by driving the feed motor 38 under the control of the servo control circuit 37 based on a command from the disk control unit 12. The reproduction signal output from the RF amplifier 35 is supplied to the servo control circuit 37, and servo control is performed to follow the reproduction track. Further, rotation drive by the spindle motor 33 is also performed under the control of the servo control circuit 37.

The recording system is configured so that the analog audio signal obtained at the recording signal input terminal 45 is converted into digital data by the analog / digital converter 46, and then this digital data is compressed / expanded by the compression / expansion processing circuit 42. A compression process is performed, compressed audio data is supplied to the memory controller 40, and is temporarily stored in the RAM 41 connected to the memory controller 40. And this RA

Here, the recording head 48 is arranged right above the position where the optical pickup 34 irradiates the disc 32 with the laser (on the side opposite to the disc). Then, at the time of recording, a process of recording the magnetic field generated by the recording head 48 is performed while heating the recording portion with the laser beam emitted from the optical pickup 34 to the disc 32. This recording process is called a magnetic field modulation recording method.

The disc recording / reproducing unit 30 of the present example
Since the system basically applies an audio signal recording system as it is, it is configured to record a two-channel audio signal of a right channel signal and a left channel signal. It is possible to record data of two channels (two series) that are supplied in a specific manner, and at the time of reproduction, the data of these two channels are simultaneously reproduced. Here, in the present example, by utilizing this configuration capable of recording two channels, various audio data is recorded in one channel and facsimile data (image data) is recorded in the other channel.

The disc recording / reproducing unit 30 having the above-described structure is incorporated in the information response device 10. here,
Returning to the explanation of FIG. 1 again, this disc recording / reproducing unit 3
The reproduction signal output from the reproduction signal output terminal 44 of 0 is
The signal is supplied to the modulation / demodulation unit 13 via the disk control unit 12, and the modulation / demodulation unit 13 performs modulation for transmission to the telephone line. This modulation is performed under the control of the system controller 11. Then, the signal modulated by the modulation / demodulation unit 13 is supplied to the communication control unit 14, and the communication control unit 14 receives the terminal 1
A reproduction signal is transmitted to the telephone line side connected via 5.

Further, the reception signal supplied from the telephone line side to the communication control section 14 through the terminal 15 is supplied to the modulation / demodulation section 13 to demodulate the signal modulated for transmission.
The demodulated signal is recorded on the disc via the disc control unit 12.
The signal is supplied to the recording signal input terminal 45 of the reproducing section 30 and recorded on the magneto-optical disk 32. The modulation and demodulation in the modulation / demodulation unit 13 is necessary at the time of making or receiving a call using a telephone line. The data reproduced from the disc recording / reproducing unit 30 side and the disc recording / reproducing unit 30 side The data to be recorded in is directly transmitted / received to / from the telephone line side without being modulated or demodulated.

A facsimile device 20 is connected to the communication control unit 14. This facsimile machine 20
Is commercially available because it is used by connecting to a telephone line. Then, the facsimile data (image data) of the original read by the facsimile device 20 is supplied to the communication control unit 14, and is supplied to the disc recording / reproducing unit 30 via the modulation / demodulation unit 13 and the disc control unit 12. The facsimile data can be recorded on the magneto-optical disk 32. In addition, the facsimile data reproduced from the magneto-optical disk 32 is

A monitor speaker 17 is connected to the communication control unit 14 via an amplifier 16, and the audio data recorded on the magneto-optical disk 32 is transferred to the monitor speaker 1.
It can be played back from 7. Although not shown, the audio signal picked up by the microphone connected to the information response device 10 can be supplied from the communication control unit 14 side to the disc recording / reproducing unit 30 and recorded on the magneto-optical disc 32. Is done.

Further, the information response device 10 of this example is provided with the operation keys 18 and the display section 19 so that the operation information of the operation keys 18 is supplied to the system controller 11, and the system controller 11 is currently operated. The operating state of the is displayed on the display unit 19. In this case, operation key 1
The display 8 and the display unit 19 are configured, for example, as shown in FIG. 3, and the operation keys 18 include a mode key for setting each operation mode and a ten-key pad.

That is, various keys necessary for recording information on the magneto-optical disk 32 and extracting the recorded data are arranged, and the data recording state of the magneto-optical disk 32 is displayed on the display section 19. Is done.

The magneto-optical disk 32 of this example has
In addition to digital data such as audio data, sub data can be recorded, and this sub data is recorded in a predetermined format on a predetermined track (for example, the innermost track). The sub-data recorded on the predetermined track is recorded on the magneto-optical disk 32 before recording or reproducing various data (for example, the disk 3).
2 is played back (when mounted in the recording / playback unit 30) and stored in the memory in the disk control unit 12. Then, the control of the recording address and the reproduction address when recording and reproducing is performed based on this sub data. When various data is recorded, a process of adding data such as the recorded address to the sub data (that is, a process of updating the sub data of the corresponding area) is performed. Also, only sub-data may be updated by editing work or the like. In the following description, this sub-data recording area will be referred to as a lead-in area.

The contents and data structure of the lead-in area will be described. First, as the contents of the data in the lead-in area, the address data of the track number set on the disk 32 and the data of each track number are recorded. The data of the created data type, the data of the track name given to each track number, and the data of the disc name given to the disc 32 are recorded. In addition, such data is TOC (Table of
Content: Index information).

The data in each lead-in area is divided and recorded in areas of 32 bits as shown in FIGS. The track number described here is 1 for the data recorded on the disc 32.
A number assigned to each unit, for example, when recording audio data of a plurality of songs on one disc, the number assigned to each song is an absolute number of data recording tracks formed on the disc 32. It is not directly related to the number of tracks.

The address data for each track number and the data regarding the type of recording data are recorded as shown in FIG. That is, if it is assumed that N pieces of audio data from the track number 1 to the track number N (N is an arbitrary integer) are recorded on the disc 32, the area 111 is recorded with the address data of the track number 1. Data indicating whether or not there is recorded (area 151 in this case), and thereafter, data indicating the recording area of the address data of the track numbers corresponding to the track numbers N are recorded one area at a time.

From area 151, 2 areas are 1
Used in pairs, the start address and the type data of the corresponding track number are recorded in the first area, and the end address and the connection data of the corresponding track number are recorded in the next area. In this case, as the type data, the type of recorded audio data (stereo, monaural distinction,
Presence of copy guard, emphasis on / off, etc.)
Is recorded, and the data of the track number to be reproduced next to the corresponding track number is recorded as the connection data.

The data of the track name given to each track number and the data of the disc name given to the disc 1 are recorded as shown in FIG. That is,
Data indicating in which area the character data of the track name of track number 1 is recorded (area 251 in this case) is recorded in the area 211, and the track names of the track numbers corresponding to the track numbers N are sequentially recorded one area at a time. Data indicating the recording area of the character data is recorded.

From area 251, 2 areas are 1
Used as a set, the character data of the track name is recorded using 2 areas. In this case, data such as characters and numbers is recorded as data using a 1-byte character code. Also, when the connection data is recorded last and the number of characters of the track name does not fit within the recording data amount of two areas, the data of the subsequent area number is recorded with this connection data. Therefore, the area in which the character data of one unit of track name can be recorded can be expanded by sequentially indicating the subsequent area numbers in the connection data, and the number of character data of one unit of track name is not limited. (However, there is a limit determined by the capacity of the entire sub-data recording area.)

In the area where the character data of the track name is recorded, the character data of the disc name can be recorded with the same structure. In the example of FIG. 6, area 25
1, 252 are used as the data area of the disc name.

In this example, the lead-in area in which data is recorded in this way is used, and the disc 3
The data relating to the recording state of the message data recorded in No. 2 is recorded. The data regarding the recording status of this message data will be explained below.
First, in this example, message data is recorded in the tree structure shown in FIG.

That is, in this example, boxes in which data is recorded are set in order from the box number 1 (B1) on the disk 32, and tracks corresponding to the boxes are set on the disk 32. Then, on the track corresponding to each box, voice data as guidance to be transmitted to the other party who needs information and message data (facsimile data or voice message data) required by the other party are recorded. First, on the track corresponding to the box 1, voice data as guidance to be transmitted to the other party is recorded.

Under the box B1, three options are provided, and the boxes B2, B3, B4 and B5 are connected. This is set as the information of the node N1, and this node information is recorded in the information of the track name described later. The boxes B4 and B5 are set to be used integrally.

Then, the respective boxes B2, B
Guidance to be transmitted to the other side is also recorded as voice data on the tracks 3, 3, B5, and data indicating the number of options provided under each box number is set as nodes N2, N3, N4. There is. Here, a maximum of 3 boxes can be connected under the boxes B2 and B3, and a maximum of 5 boxes can be connected under the boxes B4, B5. So below the box B2 are two boxes B
6 and B7 are set, and only two boxes B8 and B9 are set below the box B3.
Below the number 5, only three boxes B10, B11, B12 are set, and data such as guidance is recorded as voice data on the track corresponding to each box. However, here, the tracks corresponding to boxes B7 and B9 are
Message data transmitted directly to the other party by voice is recorded.

Then, the set boxes B6 and B8
Further below, boxes B13 to B15 and box B1
6 is set. The number of options in each box at this stage is shown as nodes N5, N6, N7, N8.
However, since the nodes N6 and N8 do not have boxes to be set here, 0 is set as data.

Then, the boxes B13 to B1 at this stage
Below the 6, up to 9 boxes can be connected. In this case, the set number of boxes is from node N9 to
Shown as N20. However, here, the node N12-
Since N14 and N16 to N20 have no boxes to be set, 0 is set as data.

In this example, the box B13 is connected to the five boxes B17 to B21, the box B14 is connected to the five boxes B22 to B26, and the box B15 is connected to the box B15.
Are connected to the five boxes B27 to B31, and the box B16 is connected to three boxes B32 to B34. Facsimile data as message data is recorded on the tracks corresponding to the boxes B17 to B34.

The nodes N9 to N20 configured in this way
The boxes B17 to B34 connected via the are used as service data recording areas.

Below the boxes B10 to B12 connected via the node N4, a box as a reception data recording area is set, and the voice data received via the telephone line is recorded. In this case, the data is sequentially recorded in boxes (boxes B100, B200, B300 and later) set under the boxes B10 to B12.

Next, a description will be given of a structure in which the data of each node having the tree structure configured as described above is recorded as the data of the disk name of the disk 32 on which this data is recorded. First, in this example, the data of the disc name is data of 20 digits. The 20 numbers from the 1st digit to the 20th digit of the 20 digits correspond to the 20 pieces of data from the data of the node N1 to the node N20, respectively. Here, since the data of each node is the data indicating the number to be connected, the node N5
In the case of up to N20, the number to be connected is recorded as it is. In addition, in the case of the nodes N1 to N4, it is possible to determine which box is connected by a number,
Set weighted numbers to be recorded.

That is, 3 connected to each of the nodes N1 to N4
When [1], [2] and [4] are set in the respective boxes and only the boxes corresponding to the respective numbers [1], [2] or [4] are set, the node data is set. If two or more boxes are set as 1, 2, or 4, the value obtained by adding the numbers 1, 2, or 4 of each box is set as the node data. Therefore, when the disk name is set from the setting state of each node data in the example of FIG. 4, the result is as follows. Disc name "755330
105555000000 "

The disc name thus set is recorded as the disc name data of the lead-in area shown in FIG.

In the track name data set subsequent to the disc name data, the data of the type of data recorded in the box corresponding to each track is encoded and recorded with numbers or characters. As the type of this data, in addition to the types of guidance voice data, voice message data, and facsimile data, in the case of facsimile data, there is data of its attribute. In the case of this facsimile data, as the attribute data, the data of the facsimile transmission mode (distinguishing G3, G4, etc.),
There are data such as paper size data and definition data. Further, if a password (encryption) is required to extract information, this password may be recorded as track name data.

In this way, by using the disc name data and the track name data in the lead-in area, the state of the tree structure and the type of recorded data of each box are recorded, so that the information response device 10 The system controller 11 can determine what kind of control should be performed only by discriminating the data in the lead-in area read from the disc when the disc is mounted, and the control is simplified. That is, the system controller 11 controls the reproduction track when there is an incoming call through the telephone line connected to the terminal 15 based on the data in the lead-in area read by the disk control unit 12. There is. In this case, the instruction from the other party is given by the DTMF signal transmitted by the operation of the push button of the other party's telephone, and the DT transmitted by the system controller 11 side.
The MF signal is discriminated and the information to be transmitted is controlled.

In the case of a disc recording / reproducing system using a mini disc, there is a system in which the disc name and the track name can be easily set by operating the keys of the recording / reproducing device. In the case of the above, these settings can be set by using a ten-key pad or the like prepared as the operation key 18. Further, when the facsimile data is recorded on the disc, the facsimile device 20 connected to the information response device 10 is used. That is, an original document to be provided as information is read by the facsimile device 20 to form facsimile data, and the facsimile data is recorded on the disc 32 mounted on the disc recording / reproducing unit 30.
In this case, when the facsimile data is transmitted from the facsimile device 20, the CN is first transmitted as in the case of transmitting the facsimile data via a normal telephone line.
A calling tone called a G signal is transmitted to tell the other party to transmit the facsimile data, and the facsimile data is continuously transmitted only when there is a corresponding response. Therefore, when the communication tone is received from the facsimile device 20, the communication control unit 14 responds so as to receive the facsimile data, and records the transmitted facsimile data in the track of the box number operated by the operation key 18. Let Further, when the facsimile data received via the telephone line is recorded on the disk 32, the same procedure is performed.

When the facsimile data is recorded on the disc 32, the data stored on the disc 2
Only one channel is recorded in the recording area of the channel. Therefore, in the system controller 11, when the communication control unit 14 determines that the calling tone is received, it is determined that the data to be supplied subsequently is the facsimile data, and the disc 3
Control is performed so that recording is performed on one of the two channels.

Information to be transmitted to the other party by voice is recorded on the disk 32 using a microphone (not shown) connected to the information response device 10. At this time, under the control of the system controller 11, only the other channel is recorded in the recording area of 2 channels prepared on the disc.

Next, an example of using the information response device 10 of this example in the tree configuration shown in FIG. 4 will be described. It is used here to provide catalogs of video and audio equipment manufacturers. First, a person who needs the catalog dials to connect to the information response device 10, and connects through the telephone line. When the information response device 10 receives a call, the voice guidance recorded in the track corresponding to the box B1 is first reproduced and transmitted to the other party. At this time, guidance is required to select the required information. For example, "This is a telephone information service of XX company. If you want information on video equipment, number 1; if you want information on audio equipment, number 2.
If you have an opinion or request for our company, please press No.3. ".

When the other party presses the push button of any number in accordance with this voice instruction, the corresponding DTMF signal reaches the information response device 10 and the corresponding box number (box number) connected to the box B1 via the node N1. B2, B
(3, B4, B5) guidance is reproduced.
For example, if the other party presses the No. 1 push button, the voice guidance recorded in the track corresponding to the box B2 is reproduced and transmitted to the other party. In this example, for example, "If you want a catalog of video equipment, press No. 1. If you want to know new product information of video equipment, press No. 2."

If the other party presses the first push button at this stage, the voice guidance recorded on the track corresponding to the box number B6 is reproduced,
Send to the other party. For example, "Please press No. 1 if you want a catalog of VCR, press No. 2 if you want a catalog of a video camera, and press No. 3 if you want a catalog of a video disc player."

At this stage, if the other party presses one of the push buttons, the box number B6 and the node N5
Three boxes B13, B14, B connected via
The voice guidance recorded in the track of the corresponding box number of 15 is reproduced, the box in which the catalog of the required model is recorded is selected, and the facsimile data of the required catalog is reproduced from the disc 32. , Is transmitted to the other party via the telephone line, and is printed out on paper by the facsimile device connected to the other party's telephone.

For example, if the opponent pushes the first push button at this stage, the next guidance recorded on the track corresponding to the box number B13 is reproduced. "It's a catalog of VCRs. Catalog number XX is 1
Please press No. 2 for Catalog No. and No. XX, No. 3 for Catalog No. XX. ", And then the other party presses one of the push buttons, box B17 connected to box number B13 via node N9.
The facsimile data recorded in the track of the corresponding box number in B21 to B21 is reproduced from the disk 32 and transmitted to the other party via the telephone line.

When transmitting the facsimile data, the system controller 11 determines the data of the track name of the track on which the facsimile data is recorded, and determines the type of the facsimile data (paper size, transmission mode) and the like. The communication control unit 14 causes the communication control unit 14 to send out a calling tone containing the information, and informs the facsimile apparatus of the other side to transmit the facsimile data, and then causes the facsimile data to be transmitted.

If the other party pushes the No. 2 push button corresponding to the new product information of the video equipment at the stage of transmitting the voice guidance of the box B2, the track of the box B7 connected via the node N2. Move on to playback of the sound recorded in. Here, for example, "A new video camera will be released on x month x day. The features of this product are ...
, Etc., and announce the new product information by voice.

At the stage of box B1, the node N1
In the process when the box B2 connected via the is selected, when the box B3 is selected, the same procedure is performed.
Facsimile data of catalogs related to audio equipment is transmitted according to voice guidance. The processing up to this point is related to the service data recording area in the tree structure of FIG.

Then, when the operation for moving to the boxes B4, B5 side (that is, the reception data recording area side) is performed at the stage where the voice guidance of the box B1 is played, the voice guidance recorded in the boxes B4, B5 is changed. To play.
Here, for example, "If you have an opinion about our products, please give us the number 1
No., if you have other requirements, please press No. 3. "
And play.

If any push button is pressed at this stage, the process moves to any box connected via the node N4. For example, if the other party presses No. 1 at this stage, the process moves to box B10, the voice guidance recorded in this box B10 is reproduced, and then the voice spoken by the other party is recorded in the corresponding track of the disc 32. Here, for example, let's say "Your opinion about the product. Please tell us your opinion when you hear a beep. If you let us know the contact information, we will reply later.", And then the voice received via the telephone line Are recorded on the disk 32.
At this time, since the audio data is recorded, it is recorded on the other channel in the recording area of 2 channels prepared on the disc 32.

In this way, the received data is sequentially recorded in the reception data recording area, and an individual box number is set every time one unit of recording is performed.

When the voice recorded in this way is reproduced on the information response device 10 side, the operation key 18
In accordance with the operation of, the reproduction is performed from the monitor speaker 17 connected to the communication control unit 14, but only the recording data of the other channel in the recording area of 2 channels prepared in the disk 32 is sequentially reproduced. By doing so, it is possible to reliably reproduce only the voice data, and the facsimile data recorded in one channel is not reproduced as voice, and unnecessary reproduction is not performed. Further, even when the cartridge 31 in which the disc 32 is stored is detached from the information response device 10 and mounted in another audio mini disc reproducing device, setting is made so that only the other channel is reproduced. Then, it becomes possible to play only the voice.

By thus operating the information response device 10 of the present embodiment, various information can be transmitted as a hard copy or voice by facsimile, and an information transmission device for providing information service by telephone can be easily constructed. be able to. In this case, since the disc recording / reproducing unit 30 incorporated in the information response device 10 uses the digital audio signal recording / reproducing system using a magneto-optical disc called a mini disc as it is, it can be constructed at a low cost. it can.

Further, since the data defining the tree structure is encoded and recorded in the lead-in area defined by the recording / reproducing system of the mini disk, the data relating to the tree structure is directly recorded on the information response device 10. Appropriate control can be performed only by the controller determining the data in the lead-in area without performing an input operation. Therefore, the service content can be changed by simply removing and replacing the cartridge in which the disc is stored. Therefore, it is possible to change the service contents without preparing any other complicated key operation by preparing a plurality of discs in advance and exchanging the cartridges appropriately. No longer needed.

Further, for example, at least one person at the head office side can use the information service data by copying a disk of the same content at the head office side and sending it to each branch office and mounting it in the information transmission device prepared at each branch office. If there is a person who has the knowledge to make a disc on which information is recorded, each branch can easily provide the same information service. Note that in this case, for the duplication of the disc, an audio mini-disc recording / reproducing device can be used, and it is not necessary to prepare a dedicated duplicating device.

Further, in this example, since data such as voice received by the tree structure can be recorded on the same disk, it can be used as a message device such as an answering machine, and the range of use of this device is expanded. In this case, although only the voice is recorded in the above embodiment, the received facsimile data or the like may be recorded.

In the above-described embodiment, the telephone line is connected to transmit the information to the other party connected to the telephone line. However, the information response device is not connected to the telephone line. The connected facsimile device 20 may be operated by an unspecified number of people so that the person who operates the facsimile device 20 can retrieve the information recorded on the disk 31.
