A tape recorder 1IiI that performs measurement, calculation, storage, etc., and controls the operating state of the tape recorder 6 according to the results.
Part II11 includes a disk player control command means 14 which outputs a command for controlling the disk player 1 when operation control of the disk player 1 is required depending on the state of the tape recorder 6.

The operation of the embodiment of the present invention configured as described above will be described below with reference to FIGS. 2 and 3.

FIG. 2 is a flowchart showing the operation of the disc player, and FIG. 3 is a flowchart showing the operation of the tape recorder.

First, a disk on which music consisting of a plurality of songs and information such as the playing time of the music are recorded as digital signals is loaded into the disk player 1, and a magnetic tape is loaded into the tape recorder 6. Next, input a command to start playing the disc on the disc player operation unit 4. Step 1)
The disc player control unit 5 receives this reproduction start command and causes the optical pickup 2 to start reading information on the disc. Of the read information, the music signal is output as an analog audio signal by the signal processing circuit 3, and information such as the playing time of the music is input to the disc player control section 5 and stored. In this way, the disc player 1 starts playing the disc, but at the same time, the tape recorder control command means of the disc player control section 5 outputs a recording start command to the tape recorder 6 (
Step 2) The tape recorder control section 12 receives this recording start command (step 20), issues a command to start recording operation to the magnetic recording circuit 7 and tape running drive section 8, and in response to this command, tape running is driven. Section 8 runs the magnetic tape. At the same time, the music signal reproduced by the disk player 1 is recorded on the magnetic tape running by the magnetic head through the magnetic recording circuit 7 (step 21).

When the recording operation of the tape recorder starts in this way, the reel rotation detection section 9 detects the rotation of the tape take-up reel of the tape running drive section 8 due to tape running, and generates a pulse signal corresponding to the rotation speed. This pulse signal is input to the tape recorder control section 12, and the edge of the pulse signal is counted up (step 22).Also, in the process of playing back a plurality of songs recorded on the disk, the disk player l When the beginning or end of each song comes, the disk player control section 5 sends a song start signal or a song end signal to the tape recorder 6 (steps 4.5, 7.8).This song start signal is sent to the tape recorder. At the same time as the control section 12 receives the edge of the pulse signal generated by the reel rotation detection section 9 as described above, the tape recorder control section 12 stores the count value at that time. Each time the start signal is sent to the tape recorder 6 (step 23)
, the tape recorder 6 stores the count value by replacing the previously stored count value with a new count value (step 26).

In this way, as the playback operation of the disk player and the recording operation of the tape recorder progress, the remaining amount of the magnetic tape decreases, and the end of the recordable portion of the magnetic tape is detected by the tape end detection section 10. Then, the tape end detection section 10 outputs a tape end detection signal (step 27).

Upon receiving this tape end detection signal, the tape recorder control section 12 outputs a reproduction-time stop command to the disk player 1 through the disk player control command means 14. The disc player control unit 5 that received this playback-time stop command,
Interrupting disc playback and performing calculations by the determination means,
As a result, if the playback time of the disc is longer than a predetermined value, the optical pickup 2 performs a search operation to access the middle of the song being played at that time to the beginning of that song, and when the search operation is completed, the disc is The player 1 is placed in a paused state (steps 9, 10.11).

If the disc playback time is less than or equal to the predetermined value as a result of the above calculation, the tape recorder control command means 11 of the disc player control section 5 outputs a mute command to the tape recorder 1. - On the other hand, the tape recorder 6 interrupts the recording operation by the tape recorder control unit 12 that receives the tape end detection signal and enters the magnetic tape unwinding state (step 27). In this unwinding state, the reel rotation detecting unit 9 The tape recorder control unit 12 counts down the edge of the pulse signal generated in The control unit 12 temporarily stops the tape recorder 6.

Next, the tape recorder 6, which has stopped at -, outputs a pause release command to the disc player 1 by the disc player control command means 14 of the tape recorder control section 12 (step 31). The disc player control unit 5, which has received this command to cancel the stop at the - time, returns the disc player 1, which is in the - time stop state, to the playback state (step 15). At the same time, the disc player control unit 5 outputs a recording start command to the tape recorder 6 using the tape recorder control command means 13. Upon receiving this recording start command, the tape recorder control section 12 cancels the paused state of the tape recorder 6 and puts the tape recorder 6 into the recording state again at the same time as the disc player 1 starts playing (step 32). In such a state of the disk player 1 and the tape recorder 6, the playback time of the song when the disk player 1 previously interrupted playback at the end of the magnetic tape matches the current remaining recording time of the magnetic tape. As follows, the disc player 1 can calculate the remaining amount of time on the magnetic tape that is currently being recorded from the playback time when playback was previously interrupted and the elapsed time when playback continues (step 16).
.

In this way, the disk player 1 calculates the remaining amount of time on the magnetic tape, and compares this remaining amount of time with the time required for the tape recorder 6 to perform the fade-out operation, and calculates the amount of time remaining on the magnetic tape. Play the song from the beginning. On the other hand, the tape recorder 6 rewinds the magnetic tape to the beginning of the song whose recording was interrupted at the end of the magnetic tape, and then records on the magnetic tape again at the same time as the reproduction by the disk player 1. Continue these actions,
As described above, when the remaining magnetic tape time calculated by the disk player 1 matches the time required for fade-out of the tape recorder 6 (step 17), the disk player 1 executes the tape recorder control command means of the disk player control section 5. 13 outputs a fade-out operation command to the tape recorder 6 (step 18). The tape recorder control unit 12 that receives this fade-out operation command controls the input volume of the magnetic recording circuit 7 to fade out the input level of the song being recorded by the tape recorder 6 until the end of the magnetic tape is reached. go(
Step 34). Further, the tape recorder 6 receives a mute command from the tape recorder control command means 11 described above.
By restarting the no-signal recording while operating the muting means provided in the magnetic circuit 7, the magnetic tape is rewound to the beginning of the song where recording was interrupted at the end of the magnetic tape. Erase information.

As described above, according to this embodiment, the disk player 1 plays back a disk on which music, etc. consisting of a plurality of songs are recorded, and while the tape recorder 6 is recording the played songs, the magnetic tape When the end of the tape is detected by the tape end detection unit 10, the disc player 1
The playback is interrupted and the determination means performs calculations, and if the playback time of the disc is equal to or greater than a predetermined value as a result, the optical pickup 2 is returned to the beginning of the song being played at the time and paused. On the other hand, after detecting the end of the magnetic tape, the tape recorder 6 interrupts recording, and in response to a song start signal received in advance from the disk player 1, winds the magnetic tape back to the beginning of the song where recording was interrupted, and then pauses. In this state, you can easily calculate the remaining time of the magnetic tape from the playback time of the song when the end of the magnetic tape is detected, so if you play and record the same song again from this state, you can To automatically set the timing of a fade-out operation of a tape recorder 6 from the calculated remaining time of a magnetic tape even if the recording time is not known, and to surely perform disk playback and recording such that the fade-out occurs before the magnetic tape. I can do it. Further, if the playback time of the disc is less than the predetermined value as a result of the above-mentioned calculation, the tape recorder control command means 11 of the disc player control section 5 outputs a command to hemute the tape recorder 6 (step 19), and the muting means is activated. By restarting the no-signal recording from the beginning of the song that was interrupted during operation (step 30), the previously recorded music, etc. can be erased.

In addition to setting the fade-out operation timing by calculating the remaining amount of time on the magnetic tape from the playback time of the disk when the end of the magnetic tape has been reached as in the above embodiment, it is also possible to set the fade-out operation timing according to claim 2. Like the information reproducing/recording device described above, it counts the distance the magnetic tape has traveled, stores the count value when the end of the magnetic tape is reached, and then re-records the information whose recording was interrupted at the end of the magnetic tape. Sometimes, it is possible to calculate the remaining amount of the magnetic tape from the stored count value, and by setting the fade-out operation timing based on this, it is possible to perform disk information reproduction and recording similar to the above embodiment.

Effects of the Invention As described above, the present invention provides a disc playback device capable of selectively playing back each information block of a disc in which a plurality of information blocks, TOC information, and address information are recorded, and a disc played by the disc playback device. a magnetic recording/reproducing device capable of recording each information block on a magnetic tape; a muting means for muting information recorded on the magnetic tape; and a muting means for muting information recorded on the magnetic tape; a measuring means for counting the running distance of the magnetic tape of the magnetic recording and reproducing device during recording by the magnetic recording and reproducing device; and a count value of the measuring means at the time of the head of each information block reproduced from the disk reproducing device. a storage means for storing information, a tape end detection means for detecting the end of the magnetic tape of the magnetic recording and reproducing apparatus, and an end point for storing the count value of the measuring means when the tape end detection means detects the end of the magnetic tape. a position storage means; a calculation determination means for calculating the count values of both of the storage means and determining whether a block length of information whose recording on the magnetic tape was interrupted was less than or equal to a predetermined length; and the disk reproducing device. When the tape end detecting means detects the end of the magnetic tape while the magnetic recording and reproducing device is recording each information block reproduced from the magnetic tape onto the magnetic tape, the reproduction of the disk reproducing device is interrupted, and the calculation determining means rewinding the magnetic recording/reproducing device based on the determination content to the head of the information block where recording of the magnetic tape was interrupted;
control means for controlling the muting means to restart recording from that position and erasing the information block in which the recording of the magnetic recording/reproducing device was interrupted; If the end of the magnetic tape comes while the magnetic recording/playback device is recording the data on the magnetic tape after it is played back by the disk playback device, the leader tape can be reliably read even if there is no recording time information based on the length of the magnetic tape. Disc information can be reproduced and recorded in such a way that the level of the information block recorded before the disc is gradually lowered and narrowed down, that is, it is faded out.

Furthermore, even if you record the fade-out before the leader tape, if the length of the information block is extremely short, you will not be able to determine the content even if you play it back and ask questions, which will cause discomfort. Editing effects can be enhanced by erasing parts.
