BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram IC card and an information management method thereof, and more particularly to a hologram I including a hologram ROM storing contents and an IC chip for managing information of contents.
The present invention relates to a C card and its information management method.

[0002]

2. Description of the Related Art Conventionally, a magnetic recording medium such as a floppy (registered trademark) disk or a video tape, a CD-RO has been used as an information recording medium for recording information and putting it on a distribution channel.
Optical recording media such as M and DVD (Digital Video Disk) are known. For example, contents such as movies are stored on video tapes or DVDs and distributed to consumers via distribution channels. Since the price of recording media is very low, the price almost equal to the content charge is that of a video tape or DVD.
It is imposed and distributed on the market. Also in the rental business, we decide the rent for each content, limit the period,
A method of lending a recording medium is adopted. Since DVDs have high-quality images, are lightweight and have excellent operability, they are expected to become increasingly popular in this field. D
While the storage capacity of VD is 4.7 GB at present,
Development of a next-generation DVD (25 GB class) that improves the capacity several times is underway.

An ultra-large capacity laminated waveguide hologram memory has been devised. It is classified as an optical recording medium similar to a DVD, can be mass-produced, and can be manufactured at low cost, and thus can be used as an information distribution medium. Since the laminated waveguide hologram memory is not a bit-by-bit sequential read such as a DVD, but a two-dimensional batch read capable of high-speed transfer, it is a favorite of the next-generation ultra-large-capacity memory in combination with its large capacity. Has been regarded. For details, see JP-A-11
JP-A-345419 discloses a read-only multiplex hologram information recording medium in which single-mode planar optical waveguides are stacked in multiple layers. This recording medium adopts the two-dimensional batch reading method as described above, and does not require the rotation of the recording medium unlike the reading of DVD, so that it is compact and portable such as credit card size, business card size, stamp size, etc. It can take an excellent form. For example, it is described that when 100 planar optical waveguide layers having a business card size are stacked, the storage capacity is about 130 GB.

On the other hand, magnetic cards and IC cards are known as card type information recording media. These do not store large-capacity contents such as images as in the optical recording medium described above, but authentication and billing management such as personal identification information of the person who owns the recording medium, transportation fare, telephone usage fee, etc. Often used for. The magnetic card records information on a magnetic tape attached to the card, and although it is easy to manufacture and can be mass-produced, it has a drawback that it has a very small storage capacity and is relatively easy to forge. The IC card records information on an IC chip built in the card, and has a characteristic that its storage capacity is sufficiently larger than that of a magnetic card and it is difficult to forge. However, since the bit unit price is expensive, there is a problem that it is necessary to give a sufficient added value to the recorded contents.

[0005]

A large amount of various contents can be stored in the read-only multiplex hologram memory. For example, in a card-type read-only multiplex hologram memory, an MPEG2 (Moving Picture Experts Group)
-2) can store 20 2-hour movies, and MPEG-1 can store 70 2-hour movies. Therefore, although the price of the reproduction-only multiplex hologram memory alone is low, the total price including the content charge becomes very expensive. The user does not always want to watch all the movies stored in the purchased read-only multiplex hologram memory.

On the other hand, static information such as voice information such as music, computer programs such as game software, map information, etc., has a smaller amount of information per case than dynamic content such as movies. . Therefore, since a huge number of contents are stored in the reproduction-only multiplex hologram memory, if the access right is managed for each content or the content is charged for each content, the amount of information for the management becomes enormous. As described above, although the reproduction-only multiplex hologram memory can store a large amount of information, it has a problem that it is too large as a distribution unit of contents.

The present invention has been made in view of the above problems, and an object thereof is to store a large amount of contents and to easily manage the information of the contents, and a method of managing the information. To provide.
