Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite information record carrier, and more particularly to a composite information record carrier on which visual information is displayed on the surface.

[Background of the invention]

BACKGROUND ART Conventionally, music recorded on record carriers such as records, tapes, and compact discs have been sold in large quantities, and users purchase software for these media and play them using playback devices.

[Purpose of the invention]

Therefore, it is preferable for the user to know the outline or part of the content before selecting the software.

Furthermore, it is preferable for the user to select software from as much information as possible.

For these reasons, sellers actually play the software in stores or provide information in pamphlets, but in-store playback reduces the commercial value of the software, and providing information in pamphlets I can't give you a sufficient feeling.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an information record carrier comprising complex information.

[Summary of the invention]

According to the present invention, the above object is to provide a composite information record characterized in that visual information is displayed on at least a part of the surface and information related to the visual information is recorded. This is achieved by a carrier.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described based on the drawings.

FIGS. 1a+ and tb+ are diagrams showing a schematic structure of a promotion card for promoting a singer, which is an embodiment of the present invention.1. FIG. 1 (al indicates its first surface, and FIG. 1 (bl indicates its second surface).

As shown in FIG. 1(a), on the first side of the card of this embodiment, a photograph of the singer, the signature of the singer, the title of the information recorded on the card, etc. are printed.

Information to be optically reproduced is recorded on the second side of the card of this embodiment. FIG. 1 (bl) shows the format of the recording. FIG. 2 shows a partially enlarged view.

In these figures, there is a recording area 2 on the second side of the card 1.
is provided, and the recording area consists of a plurality of blocks 3. Each block consists of a plurality of tracks 4, and each track has a plurality of recording bits 5, which are the minimum information unit.
Consists of elements arranged in the direction. Each trunk 4 also includes a preamble section 6 for obtaining a reproduced clock, a reference section 7 for indicating the start of the information track section and for identifying the track from an adjacent track in the A direction, an information track section 8, and the information track section 8. It consists of an end bit section 9 for indicating the end of the track section and for identifying the track concerned from adjacent tracks in the A direction.

During playback of the card 1 having such a recording format, an optical system forms an image on a one-dimensional sensor array for each trunk 4, and signals are read out by scanning in the C direction using the -dimensional sensor array. It is moved in the direction A relative to the -dimensional sensor, and signals are read out from new tracks one after another.

FIG. 3 is a schematic diagram of a reproducing apparatus used for reproducing the above-mentioned cards. In this figure, the card 1 is reciprocated in the A direction (ie, the direction in which the trunks 4 are lined up) by a belt drive 10.

Light emitted from a light source 11 such as an LED is collected by an illumination optical system 12 and illuminates the second surface of the card 1.

The thus illuminated image of the track 3 of the card 1 is projected onto the one-dimensional sensor array 14 by the imaging optical system 13.
Signal reading is performed by the sensor array. Furthermore, 1
Reference numeral 5 denotes an optical head including 11 to 14, and the optical head can move in the C direction (ie, the length direction of the track 4°).

The information recorded on the second side of the card 1 of this embodiment is audio information, and includes a message from the singer whose photo is displayed on the first side and a part of the song sung by the singer.

FIG. 4 is an enlarged schematic diagram of one block 3 of the recording area of the recording format of the card of this embodiment, and is particularly for explaining the information track section in detail.

In this figure, the track 4 at one end in the six directions is the leading track 20, and information indicating that it is the leading part of the block, block number, etc. is recorded in the leading track.

140 consecutive trunks 40 from the track following the first track 20 are taken as audio information tracks 21. still,
The information track section 8 of one track has a capacity of 8 bytes, of which 6 bytes are used as the audio information section 8a and the remaining 2 bytes are used as the error correction information section.

Four consecutive tracks 4 following the audio information track 21 are used as error correction tracks 22.

The size of the recording bit 5 is about 10×IO μmt, and the size of the card of this embodiment is the size of a business card, and 2145 blocks 3 having the structure shown in FIG. 4 are provided. Therefore, in this embodiment card, the amount of audio information recorded on all audio information tracks is 6X1.
It is 40X2145-1B01800 bytes. This audio information is modulated and recorded using pulse code modulation (PCM). The sampling frequency in the modulation is 20kllz, 8-bit encoding is performed, and 4 bits are encoded.
If compressed into bits, 20000X4 = 80
000 bps (bit per 5 seconds)
becomes.

Therefore, in a card with a capacity of 1801800 bytes in this embodiment, 1801800×8÷80
000#180s, that is, approximately 3 minutes of audio information is recorded.

According to this example card as described above, the user can first intuitively select the desired singer by looking at the photo on the first side, and then play back the recorded information on the second side of the card. By doing so, you can actually listen to the message of the singer, the list and explanation of some of the songs sung, and even the core part of the song.

FIG. 5 is a diagram showing a schematic configuration of a system for reproducing audio information recorded on the second side of the promote card of this embodiment as described above.

In FIG. 5, 16 is a playback device as shown in FIG. 3, and 17 is audio output means, such as earphones, connected to the playback device. Note that other speakers may be used as the audio output means 17, and the speaker may be built in the playback device 1G.

In the above embodiment, a promotion card for promoting a singer was used as an example of the composite information record carrier, but the present invention further provides that the visual information displayed on the first side of the card is a picture,
These are maps, patterns, etc., and also include those in which audio information explaining the information is recorded on the second side.

Further, in the above embodiments, the case where the composite information recording carrier is card-shaped is exemplified, but the carrier of the present invention may be other than card-shaped, for example, disk-shaped. Furthermore, the present invention is applicable to a second surface in which information is recorded not only by the difference in light reflectance, but also by the direction of magnetization, or by the concave and convex focus. It can be similarly applied to etc.

〔Effect of the invention〕

According to the present invention as described above, since visual information and information related to the information can be obtained, information selection becomes extremely easy, and particularly when used for advertisements or digests, it exhibits a great information transmission effect. be able to.
