Patent ID: 7215612

Claim:
A disk recording apparatus for recording data on an optical disk composed to have a wobble PM (Phase Modulation) format, comprising: means for detecting a first synchronous signal to be modulated into a reproduced wobble signal and indicating the head of a first data component unit and first address information contained in data composition; means for detecting a second synchronous signal to be modulated into a reproduced track signal and indicating the head of a second data component unit and second address information contained in data composition; first selecting means for selecting a detection timing of said first synchronous signal or a detection timing of said second synchronous signal or second address information; second selecting means for selecting said first or second detection address; and control means for specifying a linking position in synchronous to wobble positions on said disk, based on a selected detection timing sent from said first selecting means and a selected detection address sent from said selecting means and controlling a recording operation for a recording target track section.
