Optical disk device and method of control of an optical disk |
摘要 |
An optical disk device capable of increasing access speed and an image pickup device having such an optical disk device. In a region at the inside of an optical disk where the rotational speed of the spindle motor reaches its limit, a CAV mode is used for access, while in a region at the outside of the optical disk where a frequency band of an RF signal processor reaches its limit, a CLV mode is used for access. High-speed access to a maximum extent in a range of performance limits of the spindle motor and the RF signal processor is achieved.
