Abstract: According to the type of each of a plurality of external input interfaces, it is decided whether digital watermark information is to be detected from data entered via the external input interface. Digital watermark information is not detected from data entered via the external input interface and from which it has been decided not to detect any digital watermark information, but the data is recorded. Thus, there can be provided a data recording apparatus which is not applied with a any heavy load owing to the omission of any unnecessary detection of digital watermark information.

Abstract: On a data recording medium which is divided into sectors and can be accessed on the sector unit basis, when encoded data is divided every predetermined length, a header is added, the data is packetized, a header is further added to the packet to thereby form the pack data, and the resultant data is recorded, if the stuffing is necessary, the stuffing data is inserted to the last of a data area of the packet. Thus, a length of pack header can be fixed. There is no need to provide a padding packet. A situation such that a PES header is encrypted is prevented and no problem occurs when encryption is performed.

Abstract: Data is recorded in a first part in accordance with a signal format equivalent to that of an existing CD at the lower limit of an allowable value of a track pitch and the lower limit of linear velocity, so that data can be recorded in the first part for the maximum regeneration time. An existing CD reproducing apparatus can reproduce the audio data recorded in the first part. Compressed and encrypted audio data is recorded in a second part at a single density or at a double density. The single density represents a recording density equivalent to that of an existing CD and the double density represents a density two times larger than the single density. Audio data recorded in the second part is charged when reproduced to protect copyrights. The format of the data recorded in the second part uses the format of a CD-ROM.

Abstract: A recording medium has a first area in which data encoded with a first error correction code is recorded and a second area in which data encoded with the first error correction code and data decodable with a second error correction code that is different from the first error correction code are mixedly recorded. Data that causes the cumulated value of a DC component per unit period of data reproduced from the second area to deviate is recorded in the second area.

Abstract: Data is recorded in a first part PA1 in accordance with a signal format same as that of an existing CD at the lower limit (1.5 μm) of an allowable value of a Wreck pitch and the lower limit (1.2 m/sec) of a linear velocity. As a result, the data for the maximum regeneration time (74.7 min) can be recorded in the first part PA1. An existing CD reproducing apparatus can reproduce the audio data recorded in the first part PA1 with no problem. Moreover, compressed and encrypted audio data is recorded in a second part PA2 at a single density or a double density. The single density represents a recording density same as that of an existing CD and the double density represents a density two time larger than the single density. Furthermore, the audio data recorded in the second part PA2 is charged when reproduced in order to protect copyrights. The format of the data recorded in the second part PA2 uses the format of a CD-ROM.

Abstract: Main data and a sub code supplied from input terminals 1a and 1b are processed by encoders 2a and 2b, respectively. The encoded main data and sub code are supplied to an EFM modulating portion 4 through a multiplexer 3. The EFM modulating portion 4 is composed of an 8-14 converting portion 5a and a connection bit selecting portion 5b. For the EFM modulating portion 4, a DSV normal controlling portion 7a and a DSV special controlling portion 7b are disposed. In only a predetermined region designated on an optical disc, the DSV special control is performed. The DSV special control causes the absolute value of the DSV to increase so that data will be prevented from being normally reproduced. The normal control causes the absolute value of the DSV to converge at 0. When data is reproduced from the optical disc, if the reproduction state of the predetermined region is abnormal, it is determined that the disc is an original disc. An encryption key can be recorded in the predetermined region.

Abstract: An optical recording medium having plural recording layers includes a first recording layer on which first data is to be recorded and a second recording layer on which second data is to be recorded. The first and second recording layers are layered, with the second data being recorded at a location in the second recording layer in the vicinity of a location in the first recording layer where the first data relevant to the second data is recorded. Replay signals of variable configurations can be obtained by suitably synthesizing data read out from the respective recording layers.
