| 摘要 |
The invention is an optical disk apparatus including a generating unit which generates an RF signal and a wobble signal detected from the optical disk, a detection unit which detects a sink or a VFO on the optical disk on the basis of the wobble signal, an adjustment unit which adjusts the RF signal on the basis of timing of the detection signal detected by the detection unit, and a processing unit which reproduces the RF signal adjusted by the adjustment unit. In the optical disk of the invention, adjustment of an RF signal and the like can be easily performed by recognizing a VFO position, even in a header is not provided like the next-generation DVD-RAM.
