Recording method and disc recording equipment

Abstract

Disclosed are a writing method and a disk recording apparatus for maintaining reproduction reliability relative to a rewritable disk recording medium of a zero link type. In one embodiment, a disk recording apparatus for a rewritable optical disk comprises a first timing detector having a first timing synchronized with a wobble reproduction signal of the rewritable optical disk, and a second timing detector having a second timing synchronized with a track reproduction signal of the rewritable optical disk. A phase difference detector is configured to detect a phase difference between the first timing and the second timing. A controller is configured to determine a recording area based on the detected phase difference. In another embodiment, a selector is configured to select a timing between the first timing and the second timing. A controller is configured to control the selector to select the timing based on the detected phase difference, and to record data on a recording track in accordance with the selected timing.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims priority from Japanese Patent Application No. 2002-375848 filed on December 26, 2002, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a recording method and disk recording apparatus, and more particularly, to a recording method employed when a rewritable disk recording medium is used in a computer, and to a disk recording apparatus using the recording method. Background technique [0004] DVD-RAM, DVD-RW, DVD+RW and CD-RW are well known rewritable optical disc recording media. But for one of these media employed in a computer just like a hard disk drive, the reproduction reliability of recorded information must be sufficiently ensured. [0005] A process for linking recording tracks recorded with information is used for additional writing or rewriting of information. For example, when a CD-RW is use...

Problems solved by technology

However, the same problem arises when rewriting for each ECC block is performed for a recording track in which the frame is shifted to the rear of the distance yT from the wobbled position

[0019] In addition, since the DVD and the CD are detachable recording media, reproduction compatibility between the disk drives should be maintained, and a phenomenon must be prevented in which the drive cannot reproduce the recording when the frame is shifted. written data on disk
