Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card-like recording medium, and particularly relates to a card-like recording medium having different types of information recording areas in which information is recorded or information can be recorded and reproduced. It is something.

[Prior Art] In recent years, many optical recording and reproducing devices using recording media such as optical files and compact discs have been proposed. Proposals have also begun to be made for a card-shaped optical recording medium (hereinafter referred to as an optical card) and a method for using the same.

Furthermore, the practical use of IC cards in which a CPU and semiconductor memory are embedded in a card-like base is also imminent.

The advantages of optical cards are that they are large (21 bytes or more) and easy to copy, and the card medium is inexpensive, but they do have some drawbacks in terms of confidentiality of information and access time.

On the other hand, although IC cards have advantages in terms of confidentiality and access time, their drawbacks are their information capacity (64 Kbit) and high cost.

Therefore, both optical cards and IC cards have limitations in their use.

[Problems to be Solved by the Invention] The present inventors have conducted research to eliminate the drawbacks of conventional optical cards and IC cards, and as a result, they have discovered that different types of information can be recorded on card-shaped information recording bodies. We discovered that by providing a storage area, it is possible to maintain the confidentiality of information with a large capacity, shorten access time, and provide a card-shaped recording medium that is highly portable and can be used for many purposes. The invention has now been completed.

[Means for Solving the Problems] That is, the present invention is a card-like recording medium characterized by having information recording areas having a plurality of different characteristics.

The present invention will be explained in detail below.

FIG. 1 is a plan view showing an example of the W configuration of the card-shaped recording medium of the present invention. In FIG. 1, 1 is a card-like recording medium, and 2 is a base made of a polymeric material such as a plastic material, glass, paper, or the like. The size is preferably the size of a normal CD card (~54cm 1 x 85mm) or the size of a mobile phone. Information was recorded on the substrate 2 using different storage methods.
Alternatively, a plurality of information recording areas A and B are provided for recording and reproducing.

For example, the information recording area A is configured with a memory that can be accessed at high speed and has a so-called highly confidential function that prevents a third party from easily recognizing the internal information. Furthermore, the information recording area B is composed of a memory with a large capacity. For example, it is desirable that the recording area A portion be an IC memory, and the recording area B portion be an optical memory.

Although two information recording areas are provided in FIG. 1, any number of information recording areas with different functions may be provided as required.

Next, as another embodiment of the card-like recording medium of the present invention, FIG. 2 shows an example in which the information recording area is removably provided on the base of the card-like recording medium.

FIG. 2 is an explanatory diagram showing a card-shaped recording body in which a part of the IC memory is removable.

Information recording areas A and B are provided on the base 2. The information recording area A is a part of the IC memory, and the information recording area B is a part of the optical memory. Information recording area B has Te, Bi, AI,
An optical recording material such as Cu or an organic dye (cyanine, squalium, etc.) is provided through a layer of carbon or the like in order to obtain contrast, and is further covered with a laminate layer 3 of polycarbonate or the like. Further, the IC memory 4 is set in the card-like recording medium by a mechanism that is inserted from the end of the card-like recording medium. Electrodes 5 for supplying power to the IC memory 4 and for exchanging signals are provided on the surface of the card-shaped recording body 1.

The method of setting the IC memory 4 to the card-like recording medium is as follows.
It may also be of the type that involves inserting and setting a bottle like a normal IC memory installation method.

On the other hand, a part of the optical memory is cheap, but a part of the memory is expensive. If part overflows, part of the optical memory can be replaced, i.e.
By attaching part of the IC memory to another card, a large amount of information can be stored in a part of the cheap memory.

Furthermore, by applying the card-shaped recording medium of the present invention to a POS system, it becomes possible to construct a completely new system.

Currently, bank POs using IC cards in foreign countries (temples)
S system is running. That's because the records at the time of shopping are I.
This is a system where information is recorded in C.

The capacity is small (usually 64 Kbit), and the card price is still high at current prices. Therefore, in order to retain a large amount of past data in an IC card, a large number of cards are required. Adopting EEFROM in IC cards,
If the method of erasing the oldest information and recording new information may not leave solid evidence for future accidents (for example, fraudulent billing, online abuse, etc.).

This point is the biggest drawback of IC cards. In the card-shaped recording medium of the present invention, this drawback can be overcome as described below.

That is, the information recording area A is an EEPROM and constitutes a part of the IC memory, and the information recording area B is constituted by a part of the optical memory.

When shopping, the user enters a PIN number at the store. The card is inserted into the information recording/reproducing device, and the PIN confirmation information is quickly accessed from the EEPROM section, and after confirming the cardholder's identity, the shopping details are input into a portion of the IC memory. Naturally, when shopping is repeated many times, a portion of the IC memory overflows, but by transferring this overflow information to a portion of the optical memory, there is no need to erase past data.

In the card-like recording body of the present invention as described above, information recording areas such as a part of an IC memory and a part of an optical memory, which are commonly used, are fixed to the base by a conventional method, or are formed so as to be detachable. Therefore, it can be easily manufactured.
