| 摘要 |
An optical disk apparatus including a waiting position determining circuit which detects physical properties of each region in an optical disk after recording or reproducing processing is finished and decides a waiting position of an optical head according to the detection, and various kinds of control mechanisms which controls a position of the optical head according to the decided waiting position in order to move the optical head, is provided. By making the optical head wait at a position before two or more tracks in an unrecorded region, the recording processing can be resumed stably and surely and the recording processing can be preferentially performed in the remaining unrecorded region.
