摘要:
An optical disc (100) is provided with a recording region where prescribed clock information (WBL) is preformatted for recording. The clock information is (i) included in a first frequency band that is definable by a first reference frequency (Fstd) (that is impossible for a conventional reproducing device to detect by a detecting method based on a self-correlation) and is (ii) defined by a frequency that is integer times the first frequency.

摘要:
When a bias power level of a recording pulse waveform is varied entirely or partially, a shape of the recording pulse wave form is varied according to the variation. For example, when the bias power level is increased, a width or an edge position of a top pulse or a multi-pulse of the recording pulse waveform is varied correspondingly. Thereby, a total heat quantity of a recording laser light is not increased, and a preferable recording characteristic is maintained.

An optical disk (100) comprises recording management areas (103, 113) in which record management data for managing data recording is recorded. The record management data includes (i) physical position information (122, 125, 126) indicating the positions of physical buffer areas in which buffer data for buffering recording operation is physically recorded and (ii) logical position information (121) indicating the position of a logical buffer area in which buffer data is logically recorded or to be recorded.
