Abstract: An optical disk (D) has a first working area and a second working area having two recording formats. Encrypted data is recorded on the second working area. Encrypting key data is recorded on the first working area. The encrypting key data is used for decoding the encrypted data. This recording technique makes easy reproduction of the recorded data quite difficult. If data recorded on a bit-formed portion can be reproduced by any means, the data signal recorded on the optical disk cannot easily be reproduced.

Abstract: An input is ciphered in at least one of a sector forming circuit 13, a scrambling circuit 14, a header appendage circuit 15, an error correction encoding circuit 16, a modulation circuit 18 and a synchronization appendage circuit 18, used for processing input data for forming a recording signal. Not only the key for ciphering itself in the circuits but also the information as to which of the circuits has been used for ciphering becomes the key for ciphering. This realizes ciphering difficult to decode by a simplified structure.

Abstract: A data recording apparatus is capable of easily preventing copying of information in that, even if information is copied, the copied information cannot be reproduced. The data recording apparatus has a terminal (2) to which encoder identification information ("ID") specific to the data recording apparatus is input, a recording unit (5) for recording at least the encoder ID on an optical disk (D), and an encoding circuit (3) for encoding, in accordance with the encoder ID, data supplied via a terminal (1) and required to be recorded so that encoded data is, together with the encoder ID, recorded on the optical disk (D).

Abstract: In an apparatus and method for optically recording on an optical disk a TV signal comprised of a color image signal and an audio signal; one horizontal period portion of an original luminance signal and one horizontal period portion of two original color difference signals from a standard TV signal are time-base-compressed to generate a time-base-compressed video signal for one horizontal period, the audio signal is digitized and time-base-compressed, and then the time-base-compressed digital audio signal and the time-base-compressed video signal are time-division-multiplexed with each other and recorded on the optical disk. BACKGROUND OF THE INVENTION Field of the Invention The present invention relates generally to an apparatus and a method for optically recording color image and audio signals, and more particularly is directed to an apparatus and method of this kind which are applicable to a so-called optical Write-Once system. Description of the Prior Art It has been proposed to record a color image signal and an audio signal on an optical disk with the frequency spectra shown in Figs. 1A and 1B, respectively.

Abstract: The input is enciphered by means of at least one of a sectoring circuit (13) used for processing the input data to generate recording signals, a scramble processing circuit (14), a header adding circuit (15), an error correcting/encoding circuit (16), a modulation circuit (17), and a synchronism adding circuit (18), and the enciphered signal is outputted. In addition to the key of the enciphering itself in the circuit, which circuit performs the processing, is also an enciphering key. Therefore, data are enciphered with a simple circuit structure and ciphered data are hardly deciphered.
