Abstract

A sticker (42) having at least an encryption key (424) previously recorded in an electromagnetically and optically readable state is attached at a prescribed position of a recording medium (100). The recording medium is provided with a recording area (43) for recording data, which includes encryption data encrypted based on at least the encryption key recorded on the sticker, in the electromagnetically and optically readable state.

Claims

1-15. -15. (canceled)

16. A recording medium comprising:

a sticker, which is attached to a predetermined position of said recording medium, having at least an encryption key previously recorded on an electromagnetically and optically readable state; and

a recording area for recording data, which includes encryption data encrypted based on at least the recorded encryption key, in the electromagnetically and optically readable state.

21. The recording medium according to the claim 16, wherein

said attached sticker comprises a main part which is a part of said attached sticker, and a separated part which is other part of said attached sticker,

when said attached sticker is peeled off, the main part and the separated part are separated from each other.

29. A recording apparatus for recording data on the recording medium according to claim 16, said recording apparatus comprising:

a reading device for electromagnetically and optically reading an encryption key which is recorded on a stacker attached to said recording medium;

an encrypting device for encrypting recording target data on the basis of at least the read encryption key; and

a recording device for recording the encrypted recording target data on said recording medium.

30. A reproducing apparatus for reproducing an encryption data recorded on the recording medium according to claim 16, said reproducing apparatus comprising:

a reading device for electromagnetically and optically reading an encryption key which is recorded on a stacker attached to said recording medium, and the recorded encryption data; and

a decoding device for decoding the read encryption data on the basis of the read encryption key.
