Abstract
When reproducing a disk having a plurality of recording layers read from one face, the reading out position is refocused from the current track position in a current recording layer to the target track position in the target recording layer. The reading out position deviates appreciably during such refocusing of the reading out position, and spurt processing is performed as a result. To avoid lengthy spurt processing, the reading out position is first moved from a first recording layer to a second recording layer in which is recorded the data to be read next. Thereafter, the reading out position is moved along the second recording layer to a position where such data is located, thereby avoiding additional spurt processing.
