Optical disk recording method, optical disk apparatus, and optical disk medium

An optical disk apparatus that divides data into units of predetermined blocks and records the data in an optical disk medium,

• the optical disk medium including a track in which the data is recorded, the track being formed by wobbling and radially divided into a plurality of zones, and a clock ratio n/m (n and m are natural numbers of 1 or more) of a recording clock to a wobble clock being preset for each of the plurality of zones,
• the optical disk apparatus comprising:
• a wobble detecting circuit that detects a wobble signal corresponding to the wobbling from the optical disk medium;
• a wobble PLL (Phase Locked Loop) circuit that generates the wobble clock in which the wobble signal is multiplied by a predetermined multiplying factor;
• an ADIP (ADdress in Pregroove) reproducing circuit that identifies a present position by reproducing ADIP indicating a position of the track from the wobble signal and the wobble clock;
• a channel PLL circuit that generates the recording clock having the clock ratio n/m to the wobble clock;
• a timing interpolating circuit that identifies a data address present position located in a zone different from a recording target zone, from the present position located in the zone different from the recording target zone, a start end position of the ADIP in the recording target zone, a start end position of the data address in the recording target zone, and the clock ratio n/m, and identifies a recording start position based on the data address present position;
• and
• a recording unit that records the data from the recording start position in the recording target zone.
