Abstract:
Upon scanning with an optical spot from a first address on the first recording layer as a start point for a second address on the second recording layer which is a target address for reproducing in order to detect a reproduction position, a scanning path for reaching the second address by scanning an already recorded zone of at least one of the first recording layer and the second recording layer is selected from a first scanning path to carry out seeking after a focus jump and a second scanning path to carry out seeking before the focus jump, based on a positional relationship between a known boundary position between a not-yet-recorded zone and an already-recorded zone of the first recording layer or the second recording layer and the first address.
