[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a business card containing information in which voice information and / or image information is stored.

[0002]

[Prior art]

 Conventional business cards are printed with information such as name, company name, job title, company location, and phone number on a paper sheet of about 90 mm x 55 mm and a thickness of about 300 μm. Recently, it has been demanded to record a large amount of information that characterizes the person on a business card, and information such as textual information and photographs is used. At that time, image information such as characters and photographs is recorded by the so-called “printing method”.

There are magnetic recording media such as magnetic tapes and magnetic floppy disks, and optical recording media such as optical discs for recording audio information and image information. Although these media are optimal for storing large amounts of information, they still suffer from a bulky media volume for use as business card media. In other words, although the magnetic floppy disk is thin, it has a recording area larger than that of an optical recording medium, so there is a limit to the amount of information that can be recorded with a business card size. Further, although the optical recording medium is a high recording density medium, it has an optical disc thickness of 1.2 mm, so that it has a feeling of thickness when used as a business card. There was no medium that recorded voice information or image information on a thin sheet such as a business card.

Further, when making a call to a person who describes a business card, the number recorded as the character / numerical information on the business card is read and dialed, but it is convenient if automatic dialing can be performed using the business card. There is hope. Some business cards that can be automatically dialed are used, for example, some use a barcode, which reads the recorded barcode and automatically dials the person who describes the business card. Up to now, no one has been able to read the signal information from the business card containing the information that recorded the signal information of the other party's telephone number automatically by the optical recording method and dial it automatically.

[Problems to be solved by the device]

 An object of the present invention is to use an optical recording medium in which the size and the thickness are equivalent to those of a normal business card, and the audio information and the image information are stored in the medium. It is to realize what can be dialed to the person who describes the business card automatically when necessary.

[0006]

[Means and actions for solving the problem]

 First, a means for producing a medium in which voice information and image information are optically recorded in a business card size (about 90 mm × 55 mm) and a business card thickness (about 300 μm) will be described. Compact discs (CDs), which are generally well-known digital audio discs, are manufactured using stampers formatted by digital recording technology and injection molding technology. With this injection molding technology, it was not possible to manufacture media with a thickness of 0.5 mm or less due to the specifications and technical limits of the injection molding machine. Therefore, in the present invention, attention was paid to the thermal transfer technology as a technology for processing a sheet of 0.5 mm or less. Thermal transfer technology is a technology in which a transfer sheet is pressed together with a heated stamper, which is now available as a hologram seal. The hologram sticker can shine in a rainbow color reflecting the light due to the interference of a large number of engraved striped grooves, and can make the popular character recorded on the seal stand out. The formation of the groove is obtained by exposing the resist on glass to interference fringes and developing the resist. To make a striped groove on the seal, plate the uneven resist groove formed, make a striped stamper with uneven shape, heat this stamper and press it according to the transfer seal. can get. To produce an optical recording medium on which voice information and image information are recorded by a thermal transfer method, a hologram seal that can have a width of a stripe width, that is, a width and a depth of a groove can be produced. Since the shape of the concave and convex pits corresponding to the information, that is, the allowable width of the groove width and the groove depth is narrow, it is necessary to find the process condition and the medium material with good transferability.

A method of recording information on a compact disc (CD) is as follows. A resist layer formed into a concave-convex shape by exposing the resist on the glass with a laser beam that has been modulated according to the CD specifications for the preformatted signal, the audio signal and the image signal, and then developed. To get After that, the stamper is obtained by plating on the resist layer. Using this stamper, a medium on which information is transferred is obtained by an injection molding method. Good transferability can be obtained by the injection molding method, but good transferability is difficult to obtain by the thermal transfer method because the resin flow is small. One of the factors that enhance transferability is the groove depth. In a general CD, the groove depth after transfer is λ / 4n (λ: wavelength of reproducing laser, 780 nm in this case; n: refractive index of medium, 1.5 in case of polycarbonate) That is, the groove having a depth of about 130 nm can reproduce the information signal well. This is a valid value for media reproduced by injection molding. In the case of thermal transfer, as a result of various studies, it was revealed that good reproduction characteristics were obtained when the groove depth was about 150 to 200 nm.

Another problem in realizing a business card-shaped optical storage medium using a thermal transfer sheet is the material of the thermal transfer sheet. Since the material of the thermal transfer sheet generally needs to be moldable by a hot press, a material having a relatively low glass transition temperature is used. Examples thereof include polystyrene and polybutylene terephthalate. On the other hand, since it is an optical recording medium, optical transparency and low birefringence are also required. Polyester-based polymer materials such as polybutylene terephthalate and polyethylene terephthalate, which are good molding materials as described above, have high birefringence, and thus it is difficult to obtain good reproduction signal characteristics. As a result of various studies on the materials, it was found that the polycarbonate resin was the best.

The uneven shape of the information bit is transferred onto the sheet by the stamper and the thermal transfer sheet manufactured by the above-mentioned means, and the reflection film such as aluminum is formed on the uneven surface. If a medium with a name card size and a name card thickness in which voice information or image information is recorded is pasted on a 1.2 mm acrylic transparent substrate, sound information and image information can be recorded on a commercially available CD player or CD-ROM player. Can be played. The thickness of the business card with information is 0.4 mm or less due to the limitation of the CD-ROM player, which satisfies the sense of thickness as a business card, and the lower limit of the thickness is 0.05 mm from the viewpoint of mechanical strength and signal quality. Is.

Also, the telephone number of the person who describes the business card is recorded on the thermal transfer sheet by the optical recording method, the recorded telephone number is read by the optical reproduction method, and the telephone corresponding to this telephone number is automatically It is possible to dial.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

【Example】

 Example 1 A glass substrate coated with a positive type resist (resist thickness 150 nm) was prepared, information to be stored (sound information, image information) was digitized, and a predetermined format was made by an encoder, and a track pitch was 1.6. The resist was irradiated with a controlled laser beam so as to have a thickness of μm, and the resist layer was developed to form unevenness of information bits to be transferred on the resist layer. For the voice information, the real voice of the business card person was used for 30 seconds, and for the image information, the portrait of the business card person was used. Nickel was vapor-deposited (thickness 400 Å) on the surface of the resist layer formed in a concavo-convex shape, further nickel-plated (thickness 300 μm), peeled off, processed on the inner and outer circumferences, and back-polished to obtain a stamper. The uneven shape was transferred from the stamper and the heat transfer sheet for hologram seal (thickness: 80 μm, size: 90 mm × 55 mm, sheet material: polycarbonate) to the heat transfer sheet by a heat transfer method. An aluminum reflective film was formed on the uneven surface. As shown in FIG. 1 (a), the person's name, work place, telephone number, etc. are printed on the aluminum reflective film surface, and as shown in FIG. 1 (b), a center hole 2 of φ15 mm is formed at the center of the information recording track 1. Opened In this way, a recording medium having a business card size in which image information and voice information are recorded and having a business card thickness that does not interfere with normal use was prepared. This is called an information-containing business card. On the other hand, a polymethylmethacrylate substrate with a thickness of 1.2 mm and a hole of φ15 mm in the center was cut out to a length of 70 mm and a width of 100 mm, and the center hole of the information recording track of the information-containing business card and the center hole of the substrate were concentric. As described above, a card holder was prepared by marking a circumferential mark having a radius of 23 mm and attaching a polypropylene sheet cover having a central hole of φ20 mm. A business card storing voice information and image information was loaded in the card holder and played back on a commercially available CD-ROM player.

Although a commercially available CD-ROM player is used in the embodiment, the dedicated information processing device is, as shown in FIG. 2, an image display unit 11, a sound generating unit 12, an information reproducing unit 13, and operation buttons. Have 14.

Example 2 Under the same conditions as in Example 1 except that the resist film thickness is 200 nm, voice information (name of the business card person) and image information (portrait of the person) are recorded on a glass resist. Furthermore, voice information corresponding to the phone number of the business card person was also recorded on the glass resist substrate. This was developed to form an uneven shape, which was used as a master. Nickel was vapor-deposited on the master, and it was stamped. An uneven shape corresponding to information was transferred from the stamper and the heat transfer sheet for hologram seal (thickness 0.4 mm, size 90 mm × 55 mm; sheet material: polycarbonate) to the heat transfer film by a heat transfer method. An aluminum reflective film was formed on the uneven surface, and the person's name and work place were printed on the aluminum reflective film surface. A hole having a diameter of 15 mm was made at the center of the information recording track, the card holder was loaded in the same manner as in Example 1, and the information was reproduced by a commercially available CD-ROM player. When I connected to the phone using the phone number information that was read during playback, I successfully connected to the phone of the person who wrote the business card.
