Patent ID: 7558172

Claim:
An optical disk device recording data on a recordable or rewritable optical disk, the optical disk device comprising: zone storing means for preliminarily storing locations of a plurality of zones set by dividing a recordable or rewritable area of said optical disk from an inner periphery thereof to an outer periphery thereof; position detecting means for detecting a position on said optical disk so as to record data at said position; judging means for judging which of said zones said position corresponds to by referring to said zone storing means; and controlling means for controlling the optical disk device to perform a data-recording by a CLV (Constant Linear Velocity) method to each of the zones specified by said judging means by setting a recording velocity and a recording power for each of the zones so as to enable the data-recording to provide an equal recording density to all of the zones, wherein said data-recording is performed by packet-writing; and wherein said device further comprises: pausing means for pausing said data-recording when said data-recording is performed to an end of one of said zones; stabilizing means for stabilizing a revolving system of said optical disk so as to perform said data-recording to a next zone of said zones at the recording velocity corresponding to said next zone when said pausing is performed, said data-recording being next performed to the next zone; and restarting means for restarting said data-recording from a start of said next zone after said stabilizing is finished.
