For example, the IC memory card may be radially parallel to the thickness direction or radially in the thickness direction. It can be stored in

(Embodiment 2) The difference from Embodiment 1 is that the method of transmitting signals passed between the antenna switching circuit 21 and the transmission / reception circuit 22 of the storage case 11 is different from that of the individual I / O circuits.
The point is that it is not performed individually and sequentially with the C memory card, but is performed in parallel between a plurality of IC memory cards.

The operation for reproducing recorded contents from a plurality of IC memory cards 1 will now be described with reference to FIG.
FIG. 6A shows electrical signals (represented by 0 and 1) of contents recorded on six IC memory cards 1 from I to VI.
Are written horizontally in the order in which they are recorded in a fixed amount of electrical signal units (1 to n) for each of the IC memory cards 1 (I to VI), and are represented by a circle. By switching these electronic switches of the antenna switching circuit 21,
As shown in FIG. 6B, the electric signals are read one by one from the head electric signal of each IC memory card in order, and the ICs are arranged in the state of the arrangement of the electric signals in the same manner as in the first embodiment.
Transmit to the memory card recording / playback device. The electric signal received from the IC memory card recording / reproducing device and converted from the optical signal is transferred to the buffer memory 36 by the encode / decode circuit 33 so that the electric signal is arranged as shown in FIG. At this time, I to VI are stored in the buffer memory 36.
Are created and six directories (I to VI) corresponding to the electric signal units (1 to VI) are created in each directory (I to VI).
To n) in order. This FIG. 6 (c)
6A is the same as that of FIG. 6A, and the contents recorded on the six IC memory cards 1 from I to VI are restored on the buffer memory 36 from the head of each IC memory card. It was done.

When the contents are recorded on a plurality of IC memory cards 1, the electric signals stored in the buffer memory 36 in the IC memory card recording / reproducing apparatus are converted to the electric signals shown in FIG. 6C, the optical signal is converted into an optical signal and transmitted to the storage case 11 of the IC memory card 1. The electrical signal received from the storage case 11 and converted from the optical signal is distributed to a plurality of IC memory cards in the arrangement of the electrical signals in FIG. 6A by switching an electronic switch of the antenna switching circuit 21. .

As described above, since a plurality of IC memory cards can be recorded and reproduced from the head of each IC memory card at a time, if data is recorded at the head of the IC memory card, only the head is copied. Since the time required for copying can be reduced, the reproduction of a plurality of IC memory cards can be performed in a short time.

Only desired data may be fetched from the buffer memory 36 intermittently. (Embodiment 3) The difference from Embodiments 1 and 2 is that an electric signal transmitted to a plurality of IC memory cards 1 is
This is related to the erasure of the content already recorded on the C memory card 1.

In the IC memory card 1, in addition to voice, image, and character information, the recording time, the order of recording, and the protection state of the recorded contents (reproducible, writable, etc.) in addition to voice, image, and character information
And other management information. By rewriting the part of the management information in which the protection state of the recorded content is recorded so as to be unreproducible and writable, the already recorded data can be apparently erased. Apparently, the recorded content is simply in a state where it cannot be reproduced, and the recorded content remains on the IC memory card until it is overwritten. In other words, the recorded content of the portion where the protection status has been rewritten cannot be reproduced even if the recorded content remains on the IC memory card, and is overwritten by the newly recorded content. This method is generally used for erasing the contents of a mini disk (MD) or a hard disk.

In view of the above, the storage state of a plurality of IC memory cards 1 in a storage case 11 is used to record the protection state of the recorded contents of a desired number of IC memory cards 1 among the plurality of IC memory cards 1. The information is rewritten at a time to contents that make the recorded contents unreproducible and overwritable.

As a result, of the plurality of IC memory cards 1 stored in the storage case 11, the recorded contents of a desired number of IC memory cards 1 can be apparently collectively erased, and the time required for data erasure can be reduced. It can be shortened.
