    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: A signal recording/reproducing method and apparatus, a signal record medium, and a signal transmission/reception method and apparatus enable a signal recorded on a signal record medium to be identified as being an original signal or a copied signal. A CPU (11) generates, at a pre-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit (3) adds the identification signal to video signals and/or audio signals. A sector forming circuit (5) and circuit components up to a recording/reproducing head (14) record the video signals and/or the audio signals and the ancillary identification signal on an optical disc (12).

    Abstract: A signal reproducing apparatus, in which unauthorized decoding or copying is rendered difficult, reproduces enciphered data from a disk-shaped record medium (101) on which are recorded data enciphered by at least one encryption operation and key storage site information specifying an arraying site for at least one key information item used for deciphering the enciphered data. The apparatus includes a reproducing head device (212) for reading the enciphered data and the key storage site information from the record medium (101), a TOC decoder (219), a CPU (224) and a digital signal processing circuit (220) for decoding the enciphered data using the key information stored on the site designated in accordance with the key storage site information.
