Abstract

Data can be recorded on an optical disc at high speed and assuredly even in a case in which a recording error has occurred. In a case in which a recording error regarding data on the optical disc is detected, recording of the data is restarted avoiding recording in a predetermined range starting from an address at which the recording error has occurred, and also a recording area in which recording of the data is restarted is separated from a recording area including the address at which the recording error has occurred. When recording of the data on the optical disc is completed, information the recording area has been split is recorded in a management area on the optical disc.

Description

technical field

[0001] The present invention relates to an optical disc device and a recording control method, which are suitable for use when recording data on an optical disc. Background technique

[0002] In the past, rewritable (rewritable / -RW type) and recordable (write-once (write-once) / -R type) optical discs that allow users to freely record data have been widely used. disc drive.

[0003] In addition, for the purpose of further increasing the recording capacity, a blue laser (wavelength 405nm) with a shorter wavelength than conventional CD (Compact Disc: Compact Disc) and DVD (Digital Versatile Disc: Digital Video Disc) has been developed. ) (Blu-ray Disc) (registered trademark of Sony Corporation), which also includes rewritable BD-RE and recordable BD-R (for example, refer to patent application 2006-024287) .

[0004] In addition, in recent years, in video recording devices such as stationary video recorders and video handy cameras, it has become common to recor...
