Problems solved by technology

[0012] As described above, the conventional optical disk device has a problem that, by performing access in units of ECC blocks in the high-density recording mode, even if the number of accesses is performed less, the number of blocks with a predetermined value set on the CD standard medium will be exhausted. size of the recording area, thus, is not conducive to the effective use of the disc

Embodiment Construction

[0037] Embodiments of the present invention will now be described in detail based on the drawings.

[0038]

[0039] combine first figure 1 A schematic configuration of a system including the optical disc device 100, which is an embodiment of the present invention, is described. figure 1 The optical disc device 100 shown is an optical disc recording / reading device capable of recording and reading an optical disc (CD standard medium) 200 in a physical format conforming to existing CD standards such as CD-R and CD-RW using high-density recording addresses. In addition, the optical disc device 100 may be an optical disc readout device exclusively for reading using high-density recording addresses. The physical format is a format that provides the size of the optical disc 200, recording / reading method, sector configuration, and the like.

[0040] Here, considering the convenience of the user, it is preferable to support recording and reading from the CD standard medium in a st...

Abstract

An optical disk apparatus and its control method. The optical disk apparatus makes accesses on a block-by-block basis to an optical disk having a recording track segmented into first recording areas by first address information correlated with wobbling information of the recording track, the block being a unit for error correction consisting of a plurality of the first recording areas. The optical disk apparatus comprises an access control unit which, when an access is made to a second recording area consisting of a plurality of the first recording areas, provides access control in sequence without applying any data modulation and / or demodulation process to each of the plurality of first recording areas constituting the second recording area.

Description

[0001] Cross references to related patent applications [0002] This patent application claims priority to Japanese Patent Application No. 2003-128427 filed May 6, 2003, which is incorporated herein by reference. technical field [0003] The present invention relates to an optical disc device which ensures efficient use of a recording area of ​​an optical disc and a method of controlling the same. Background technique [0004] A typical standard for an optical disc capable of recording / reading information using a laser beam is the CD (Compact Disc) standard for data recordable (write once) CD-R, rerecordable (rewritable) CD-RW, etc. . In recent years, CD-R disks and CD-RW disks have been used more and more, and at the same time, their prices have been reduced and they have become widely popular. [0005] For an optical disc (CD standard medium) conforming to the standard physical format of CD recordable / readable, the pregroove (guide groove) wobbles (meanders) along a wave...
