Description

  The present invention relates to an optical disc having a plurality of recording layers, an optical disc apparatus for recording / reproducing data on the optical disc, and an optical disc recording / reproducing application program.

  Development of discs such as Blu-ray Disc and HD DVD, which are large-capacity media replacing CDs and DVDs, as optical disc media for storing video information and computer data in recent years, and their discs. On the other hand, an optical disc apparatus for recording / reproducing is being developed. Currently, discs with two recording / reproducing layers are commercially available for Blu-ray Disc and HD DVD, and in the future, multilayer discs having three or more recording / reproducing layers for the purpose of further increasing the capacity will be described. Development is expected to occur.

  Here, the DVD, Blu-ray Disc, and HD DVD that are currently commercially available with two recording layers are compatible with a format process that enables data to be recorded when the user records data. . In addition, it corresponds to a close process in which the user cannot add data to the disc and record it. Also, it corresponds to a finalizing process in which the user puts the recording disk into a state like a reproduction-only disk. In addition, it corresponds to a protection process in which the user cannot temporarily record data on the disc.

  On the other hand, as a conventional technique related to an optical disc having a plurality of recording layers, for example, according to Patent Document 1 below, as a method for setting an appropriate recording condition (recording waveform parameter) for an optical disc having a plurality of recording layers. It is known to select the recording layer farthest from the incident surface of the light beam and test-write data, reproduce the test-written data, and set the waveform parameters.

  However, in the conventional DVD, Blu-ray Disc, and HD DVD having the two recording layers described above, the two layers are collectively subjected to format processing, close processing, finalization processing, and protection processing. Each layer was made independent and each treatment could not be performed.

  For this reason, for example, a user has recorded 40 GB of data on an optical disk having a recording capacity of 50 GB, and 20 GB of the data has been stored, and formatting processing for newly recording 20 GB of data has not been performed. . For example, when a close process is performed after recording 20 GB data on an optical disk having a 50 GB recording capacity, the remaining 30 GB recording capacity is wasted. Further, for example, when the finalizing process is performed when data of up to 20 GB is recorded on an optical disk having a recording capacity of 50 GB, the remaining recording capacity of 30 GB is wasted. Further, for example, with respect to an optical disc having a recording capacity of 50 GB, 10 GB of the recorded 20 GB data is protected without being erased, and the remaining 10 GB data cannot be erased.

  On the other hand, in an optical disc apparatus that performs recording or reproduction on an optical disc having a plurality of recording / reproduction layers, as in the prior art, after the type of the inserted optical disc is determined, data is recorded or reproduced. , It is necessary to perform servo learning and laser power learning to correct the sensitivity of the disk. However, when data recording or playback is started after each learning is performed on all layers, The time until data is recorded or reproduced becomes longer in proportion to the number.

  Accordingly, an object of the present invention is an optical disc having a plurality of recording layers, and enables each layer to perform format processing, close processing, finalization processing, and protection processing independently or with a plurality of layers.
