Abstract

(57) [Abstract] [Purpose] A rectangular business card shape is portable and easy to store, and more effective information is transmitted by the recorded information in the optical recording section of the CD specification. [Structure] A rectangular business card is provided with a recording unit that enables optical reproduction of a CD or MD.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a business card type optical card which can be reproduced from an optical recording section provided on the card.

[0002]

[Prior art]

 Traditionally, business card and information cards have been rectangular business card size cards for portability and efficient storage of large amounts. Also, an optical card having an optical recording unit has the same shape as that of the business card or the information card.

In this optical card, recorded information is linearly recorded in order to efficiently use the card area. In linear recording, the recorded information was reproduced with a dedicated card reader that had a reciprocating motion mechanism for optical reading.

[0004]

[Problems to be solved by the device]

 However, the card reader becomes large in size and expensive, and it is difficult to use the information card in a general home or office. In addition, since it is impossible to move the information card at high speed and continuously during the reciprocating motion, the data transfer rate is slow and it is not possible to reproduce analog information such as music with high quality.

This invention solves the above-mentioned problems and ensures that a rectangular card can be easily carried and stored, and at the same time, can be played back by many CD devices that are widely used at present, so that it can be used in general homes and offices. The purpose is to provide a business card type optical card that can be reproduced in.

[0006]

[Means for Solving the Problems]

 The business card type optical card according to the present invention comprises a compact disc (CD) and / or an information recording unit capable of optical reproduction of a mini disc (MD), and has an outer shape of a substantially rectangular business card. is there.

[0007]

[Action]

 In this invention, the recording unit forms pits in a spiral shape for recording, and thus information can be reproduced by optical reading similarly to a compact disc.

[0008]

【Example】

 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a sectional view of FIG. The business card type optical card C is about the same size as a business card, and has almost the same structure as a compact disc except that the outer shape is rectangular. That is, the business card type optical card C is composed of three layers of the transparent substrate 1, the aluminum film 2 and the protective film 3, and these are made of the same material and have the same thickness as the compact disc or the mini disc.

On the aluminum film 2 of the business card type optical card C, spiral pits are provided and a recording section 5 for recording voice and information is provided. The pit size, spacing, spiral pitch, inner diameter, and information encoding method are the same as for compact discs. Also, a through hole 5 which is the same as the center hole of the compact disc is provided near the center of the spiral.

As a result, the business card type optical card C has the same optical and geometrical structure as a compact disc, and can be reproduced by a normal compact disc player.

The name card type optical card C of the present embodiment has a through hole 4 at the center of gravity when being played back by a compact disc player, so that during steady rotation, the load fluctuation of the rotation shaft support portion is small and high rotation accuracy is obtained. As a result, read errors due to the optical head are reduced, and high quality reproduced sound can be obtained.

[0012]

As described above, the present invention is a business card type optical card in which information is recorded, and since it has a recording section that can be read by the optical reading means of a compact disc, a business card, a prepaid card, etc. Since voices and information can be recorded on and reproduced by the CD player, the voice of the owner can be recorded on the business card. It also has the effect that the publisher's advertising message can be recorded along with the music on the prepaid card, and more effective information transmission means can be provided.
