Information recording apparatus, information recording method, information reproducing apparatus, and information reproducing method

摘要

An information recording apparatus for an optical information disk includes a recording position determining unit that determines a recording position on the optical information disk; and a recording and reproducing unit that performs recording and reproduction on the optical information disk. The recording position determining unit determines recording positions for all or some areas of the optical information disk, and the recording and reproducing unit records data at the recording positions on the optical information disk determined by the recording position determining unit.

主权项

1. An information recording apparatus for a servo-layerless optical information disk, the information recording apparatus comprising:
a recording position determining unit that determines a recording position format for all or some areas of the servo-layerless optical information disk from a plurality of recording position formats, determines a plurality of recording positions on the servo-layerless optical information disk as specified by the determined recording position format, and determines a plurality of addresses corresponding to the recording positions on the servo-layerless optical information disk as specified by the determined recording position format; and a recording and reproducing unit that records data at the determined recording positions on the servo-layerless optical information disk as specified by the determined recording position format, and records the determined recording position format at a predetermined position on the servo-layerless optical information disk,
wherein each of the recording position formats respectively specifies a different plurality of recording positions and addresses corresponding thereto.
