Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an information card that records voice and music on a non-circular card such as a prepaid card or a business card.

[Prior Art] Conventionally, rectangular cards have been used for information cards that are carried and stored in large quantities because of their storage efficiency. In these cards using optical recording, information was recorded linearly on the card medium. This is to improve the utilization efficiency of the card area. However, linear recording requires a reciprocating mechanism for the optical reading means, which has the disadvantage that the drive mechanism is more complex than a rotary mechanism.

[Problems to be Solved by the Invention] For this reason, the device has become large and expensive, making it difficult to use the information card in ordinary homes and offices. Also,
In reciprocating motion, it is impossible to move the information card continuously at high speed, so the data transfer speed is slow, making it impossible to reproduce analog information such as music with high quality.

This invention was made to solve the above-mentioned problems, and while ensuring the ease of carrying and storage that rectangular cards have, the large size, high cost, and slow reproduction speed of the reciprocating reproducing device. The purpose of the present invention is to provide an information card that can be played in general homes and offices by solving the problem and making it playable in devices that are currently in widespread use.

[Means for Solving the Problems] An information card according to the present invention is a non-circular card on which information is recorded, and includes a recording portion on which information is recorded in a spiral shape so as to be readable by an optical reading means of a compact disc, and the recording portion on which information is recorded in a spiral shape so as to be readable by an optical reading means of a compact disc. The disc has a through hole of the same size as the center hole of the compact disc, which is provided at the center of the spiral of the disc.

[Operation] In the present invention, a reciprocating mechanism is not required by forming pits in a spiral shape in the recording section, and information is reproduced by an optical reading means in the same way as a compact disc.

[Embodiment] FIGS. 1(a) and 1(b) are a plan view and a sectional view showing a first embodiment of the present invention. The information card 10 is, for example, about the same size as a business card, and has almost the same structure as the Combat 1 to Disk except that the outer shape is rectangular.

That is, the information card 10 has a transparent substrate 1. Aluminum film 2. It consists of three layers, the protective film 3, which are made of the same material and have the same thickness as the transparent substrate, aluminum film, and protective film in the compact disc. Further, a spiral pit is formed on the aluminum film 2 of the information card 10, and a recording section 4 in which audio and music are recorded is provided.

The pit size and spacing, spiral pitch and inner diameter, audio and music encoding methods, etc. are the same as compact discs. Since the inner diameter of the spiral of a compact disc is typically 50 mm, the width and length of the information card 10 must be larger than this value. In this embodiment, the width is 54
mm, and the length is 91 mm, so this condition is satisfied. Further, a through hole 5 having the same diameter as the center hole of the compact disc is provided near the center of the spiral. As a result, the information cart 10 optically and geometrically has the same structure as a compact disc, and is capable of playing back audio and music with an ordinary compact disc player.

In the part of the information card 10 where the pit is not formed,
The characters and figures 6 are printed with ink.

As shown in FIG. 1, the printing surface may be the upper surface of the transparent substrate 1, between the transparent substrate 1 and the aluminum film 2, or even the lower surface of the protective film 3. The size of the information card 10 of this embodiment is the same as a normal business card, so the user's name, address, etc. are printed on the characters 5 and graphics 6 of the information card 10, and the owner's voice is recorded on the recording section 4. If recorded optically, it can be used as a business card with a voice message.

FIGS. 2(a) and 2(b) are a plan view and a sectional view showing a second embodiment of the present invention. The external dimensions of the information card 1° are the same as in the first embodiment. A spiral recording section 4 and a through hole 5 are provided near the center of gravity of the information card 10, and characters and figures 6 are printed on both sides of the spiral recording section 4. When the information card 10 of this embodiment is played back on a compact disc player, the through hole 5 is located at the center of gravity, so no bending moment is applied to the rotation axis of the compact disc player during steady rotation. Furthermore, even when vibrating due to disturbance or the like, no bending moment is generated for symmetrical vibration modes. Therefore, the information card 1 of the first embodiment
Compared to case 3, load fluctuations on the rotary shaft support portion of the compact disc player are reduced and high rotation accuracy is obtained.As a result, reading errors by the optical head are reduced and high quality reproduced sound is obtained. In this embodiment, the characters and figures 6 are printed on the top surface of the transparent substrate 1, but as described in the first embodiment, they are printed between the transparent substrate 1 and the aluminum film 2 and on the bottom surface of the protective film 3. There is no harm in doing so. Also,
When the printing surface is the lower surface of the protective film 3, it is not necessary to print the characters and figures 6 while avoiding the spiral recording portion 4, and it goes without saying that all areas other than the through-holes 5 can be used.

As a third embodiment of the present invention, it is also effective to provide the through holes 5 at positions 60 degrees from two vertices, for example, P and P2. In many stationary compact disc players, the disc is not directly mounted on the rotating shaft, but a table is pulled out from the player body and the disc is placed on the table. In this case, the through hole 5 of the information card 10 needs to be approximately aligned with the rotation axis position on the table. This type of player has a circular recess with a diameter of 120 mm on the table, so if you hit the edge of this recess with two vertices p, p, located 60 degrees from the center of the through hole 5, it will automatically The center is positioned at . As a result, mounting of the disc becomes easier. Note that the vertices P and P2 are not limited to these locations and may be other vertices.

In each of the above embodiments, the information card 1o has been described as using the same material as a commercially available compact disc, but the information card 1o may be made of any material and may be combined as long as it can be played on a commercially available compact disc player. It is not a restriction. Also, 1st. In the second embodiment, the outer shape of the information cart 1o is rectangular, but the present invention is not limited to the rectangular shape, and can include a circular area with a diameter of 50 mmJJ centered on the through hole 5. It may be of any shape, such as an ellipse or a triangle. Furthermore, in the third embodiment, in addition to the above conditions, the external shape may be triangular or pentagonal as long as it has two or more vertices.

[Effects of the Invention] As explained above, the present invention provides a non-circular card on which information is recorded, including a recording portion on which information is recorded in a spiral shape so as to be readable by an optical reading means of a compact disc, and a recording portion of this recording portion. Since the spiral has a through hole of the same size as the center hole of the compact disc provided at the center of the spiral, it is possible to record audio, music, etc. on a business card, prepaid cart, etc., and to play it back on a compact disc player. Therefore, as an application of this invention,
For example, by recording the owner's voice on a business card, the owner can strongly impress the owner's characteristics on the handler. Also,
If the issuer's advertising message is recorded on a prepaid card along with music, it can be used as an inexpensive and effective means of advertising.
