Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk file device, and more particularly to a multi-head disk file device that handles multimedia such as images, audio, and text.

[Conventional technology]

In the conventional disk file device, as shown in Fig. 7,
Image data 72 recorded on track 71 of the disc.
75, audio data 73.76, text data 74.7
When reproducing multimedia data consisting of 7 pieces of data at the same time, this was done by reading the data successively using a single head. That is, multimedia data consisting of image data 72.75, audio data 73.76, and text data 74.77 is divided into finely divided tracks on a disc and repeatedly arranged in a predetermined media order. When reproducing these multimedia data, a series of data was read out continuously with a single head and distributed and processed for each media. And it was made to appear as if each media were being played at the same time.

In addition, in the conventional method of storing multimedia data on a disk, when adding two or more types of audio and text to one image, for example, adding explanations in Japanese and English to one image, In this case, as shown in Figure 8(a), multimedia data 80.85 is created in which the image part is the same but the audio and text data parts are swapped, with different numbers of audio and text types. Ta. Multimedia data for the Japanese version 80 shows the multimedia data for the Kuchihon Eki version, and multimedia data for the English version 85
indicates the English version of the multimedia data. 1'' wood version multimedia data 80, one image 8I includes Japanese audio 82 data and Japanese text 8.
3 data is added, and English version multimedia data 8 is added.
5, the same image 81 has English audio 87 and English audio 88.
is added.

[Problems to be Solved by the Invention] In the conventional method of storing multimedia data on a disk in a disk file device, when adding two or more types of audio and text to one image, it is difficult to add audio and text to the same image. Multimedia data 80°85 with only the text data part replaced was created for as many types of audio and text as possible. However, this method has the problem that image data, which has the largest amount of data, must be duplicated, and a huge data area is required.

In addition, as a method to avoid the two-legged problem, see Figure 8 (b).
I want to add to one image data 81 like [1 American English audio 825 Japanese text 83. English audio 87. A possible method is to insert data of English text 88 and select from among the data during playback. However, since the data interval of each media is determined by the playback speed,
Another problem arises in that the types of data to be inserted cannot be freely increased.

As described above, with the conventional method of storing multimedia data on a disk in a disk file device, various problems have arisen in adding many types of audio and text to one image.

On the other hand, it is conceivable to prepare a disk file device itself for each medium, but there is a problem in that controlling the disk device becomes complicated when attempting to accurately synchronize each medium.

An object of the present invention is to solve the above-mentioned problems and provide a multi-hand disk file device that can simultaneously select and simultaneously reproduce data from multiple types of data contained in each media such as images, audio, and text. There is a particular thing.

[Means for Solving the Problems] A multi-head disk file device according to the first invention includes a storage medium in which data of each medium of multimedia data is digitally stored in independent and separate media areas, and a digital and a plurality of heads corresponding to each medium of recorded multimedia data.

Further, the multi-hen 1ζ disk file device of the second invention includes data selection means for selecting each media data output from the head, and integrating the data selected by the data selection means into a predetermined order of media. and a data integration means for outputting the data.

[Effect]

In the first invention, data on each medium is independently allocated to separate areas of a disk serving as a storage medium, and a head for rough reading is prepared for each medium.

This makes it possible to simultaneously reproduce data selected from a plurality of types for each medium.

Further, in the second invention, first, necessary data is extracted from a plurality of types of data read from a head corresponding to each medium using a data selection means, and is temporarily stored. Next, the data integrating means integrates the multimedia data such as image data, audio data, and text data temporarily stored in the data selecting means in a predetermined order and outputs the integrated data. As a result, an output is obtained in which data selected from a plurality of types for each medium are repeatedly arranged in the order of the predetermined media.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram for explaining the invention in detail.

This multi-haler one-disk hub device includes an image head 15, an audio head 16, and a text head 17.
Each dedicated head reads data from the image data area 12, audio data area 13, and text data area 14 of the disk 11.

The disk 11 is a disk on which multimedia data is stored. This disk 11 is a magnetic disk,
It consists of storage media such as optical discs, CD-ROMs, and laser discs. Therefore, the disc may be read-only or rewritable. Also, an image data area 12, an audio data area 13, a text data area 1
The positional relationship of the data areas in 4 may be swapped,
If the disk device is configured with multiple surfaces, the data areas do not need to be on the same plane.

The image head 15 is a head for images, and a head for audio.
Reference numeral 16 is a head for audio, and head 17 for text is a head for text. These heads may be in any positional relationship as long as they can move independently. Further, these heads may all have the same properties, or may be composed of heads with different properties. Furthermore, in this embodiment, the number of heads corresponding to each medium may be one or more.

FIG. 2 shows the state of data stored in the audio data area 13 shown in FIG. The audio data area 13 includes a Japanese audio data area 21 and an English audio data area 22.
, the French false voice data area is divided into three parts,
Data is stored.

Next, the operation of the embodiment of the first invention will be described with reference to FIG.

For the image stored in the image data area 12, Japanese,
Considering adding explanations in English and French, if you want to listen to explanations in Japanese while drawing an image, at the same time as reading the image data area 12 with the image head I5,
The audio head 16 reads the Japanese audio data area 21 of the audio data area 13.

Similarly, in the case of English, the English audio data area 22 is read out, and in the case of French, the French audio data area 23 is read out. In this way, multiple types of audio data can be made to correspond to the same image data. Furthermore, each media can be played back at the same time.

Furthermore, as a method for storing data in the audio data area, in addition to the data storage method shown in FIG. 2, an embodiment in which a plurality of types of data are stored in the same track as shown in FIG. 3 is also conceivable. That is, in the audio data area 13,
Japanese audio data areas 21a, 21b, 2
1c, an English voice data area 22a22b, and French voice areas 23a and 23b are alternately stored. In this case, Japanese, English, and French are reproduced by reproducing data at regular intervals. For example, when playing Japanese, the Japanese audio data areas 21a, 2
By reproducing the data of 1b and 21c, only Japanese can be reproduced.

Note that in the two data storage methods described above, voice data has been described, but the same applies to text data.

FIG. 4 is a circuit block diagram showing an embodiment of the second invention, and FIG. 5 is a diagram showing an example of the data selection section of FIG.
FIG. 6 is a diagram showing data storage in each medium to explain FIGS. 4 and 5. FIG. In FIG. 4, parts having the same functions as those shown in FIG. 1 are given the same reference numerals.

Image head 15. Audio head 16. The text head 17 has the same function as the head shown in FIG. The data selection units 41a, 41b, and 41c select one type of data from a plurality of types of data read from the image head 15, the audio head 16, or the text head 17 corresponding to each media data. 5 shows the specific configuration of this data selection section. As shown in FIG. 5, the data selection section consists of a counter 51 and a memory 52. Then, the start address and stopper address data of each media data are input to this counter 51.

The data integration unit 42 receives data selected for each medium from each data selection unit 41, and outputs the data to the data bus in a predetermined order.

Next, the operation of the embodiment of the second invention will be explained in FIGS. 4 to 6.
This will be explained with reference to the figures.

Here, explanation will be given using the sound 7+i deck as an example.

Assume that the audio data is stored as shown in FIG. That is, the audio data 61 is Japanese 62, English 63, . It is assumed that the words are stored in the order of French 64.

The audio data 61 is read from the audio head and input to the counter 51 of the data integration section 41b.

The counter 5I is supplied with a start address and a stop address. For example, if audio data in English 63 is required, a start address 65 and a stop address 66 in English 63 are supplied to the counter 51. The counter 51 counts input data based on the start address 63 and the block address 66, and outputs the data from when the start address is reached to when the end address is reached to the memory 52. As a result, only desired audio data is stored in this memory 52. Therefore, in this example, English audio data is selected and stored.

By repeating the above operations, a data format in which the data of each medium is repeatedly arranged in order, as discussed in the conventional technology, can be obtained, and each piece of data of each medium can be arbitrarily selected from among multiple types. It becomes possible to do so.

In addition, in the multi-head disk file device of the present invention,
Although images, audio, and text are shown as media, the types of media are not limited to these.

〔Effect of the invention〕

As explained above, in the multi-head disk file device of the first invention, it is possible to select any type of data from a plurality of types of data in each medium and to simultaneously reproduce each medium. Therefore, there is no need to have the same data redundantly as in the past. In particular, this has the effect of significantly saving space compared to having duplicate image data.

On the other hand, in the conventional data storage method on a disk that does not have duplicate identical data, the number of types of audio data and data that can be added to images is limited by the sampling frequency of the media. In the device described above, since the area for each medium is provided independently, the above-mentioned limitations are almost eliminated.

Furthermore, since each data area exists on a disk that operates under the same control, there is an advantage that the effort required to synchronize each media is extremely reduced.

In the multi-head disk file device according to the second invention, in addition to the advantages of having two heads, the output of each head is processed into a data format in which data of each medium is repeatedly arranged in order. Therefore, there is only one output data path,
Another advantage is that it is easily compatible with conventional equipment.
