ABSTRACT:
An optical disk apparatus is disclosed which 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.
