Abstract: Audio data are read out, via an ATAPI interface, from an audio CD set in a CD drive. Thus, even where an inexpensive low-speed CPU is used, high-speed copying can be performed. When audio data stored on a hard disk are to be reproduced, and if copying authorization/inhibiting information indicates that coping of the audio data should be inhibited, the audio data are output, via a digital audio interface, with a copying-inhibiting subcode imparted to the data. Further, when the audio data stored on the hard disk are written to a CDR media set in the CD drive, the audio data on the hard disk are erased in correspondence with the writing of the digital audio data to the CDR media. With such a copying restricting feature, it is possible to provide a digital-audio-signal recording apparatus that can be properly used as consumer equipment.

Abstract: The present invention relates to method and apparatus of recording an audio signal composed of several tracks on a recording medium in a manner that the tracks can be distinguished each other in a recorded audio signal. The present track-synchronous recording method detects a no-sound interval longer than a predetermined time that is included in an input audio signal during recording the input audio signal, and records an audio signal following the detected no-sound interval with a different track number from that of recorded audio signal preceding the detected no-sound interval. Therefore, it is possible to individually distinguish tracks on a copy medium even though those not having any track information are copied thereto from an original at a time.

Abstract: A method and apparatus for copying/moving data on an optical recording medium is disclosed, in which data moves or copies in one disc using a memory and data transmission to a host is omitted when the data moves or copies in one optical disc.

Abstract: A recording medium storing a write protection information, and a write protection method for protecting data recorded on a recordable and/or rewritable disc from unwanted overwriting or erasing. In order for write protection of a disc in a bare state that is usually used in a cartridge having a recognition switch for write-protection, such as a DVD-RAM, write protection information is recorded in a Lead-in area, a Lead-out area or a recording information area other than a user data area of the disc, and the data is protected from unwanted overwriting or erasing using the write protection information. Also, even though the write protection information stored on a disc does not match the state of a recognition switch of a case for write-protection, the data can be prevented from unwanted overwriting or erasing. Thus, the write protection can be ensured when a recordable and/or rewritable recording medium, such as DVD-RAM, DVD-R and DVD-RW, is used in a bare state.

Abstract: Method and apparatus for preventing unauthorized replication of a digital data file. A plurality of second data set samples are substituted for a plurality of user data samples in a user data sequence to generate a combined data set. Error correction codes are calculated to correct errors in the combined data set. Uncorrectable errors are then intentionally written to the error correction codes corresponding to the second data set samples so that, during playback, the readback system conceals the corresponding second data set samples. An unauthorized copy of the digital data file will not include the uncorrectable errors; thus, the same readback system will output both the user data samples and the second data set samples, with the second data set samples interfering with the integrity of the user data samples.
