摘要： A method for generating a write clock of a constant angular velocity compact storage device and the device thereof. The compact storage device has a counter for generating a count number by a reference clock counting a wobble signal, and a phase detector for generating an adjustment value by comparing a phase shift between an ATIP synchronization signal and an encoded subcode frame synchronization signal. According to the count number and the adjustment value, a rectification value is found, and the rectification value and the reference clock is used for generating a reference write clock to modify the encoded subcode frame synchronization signal. If the phase shift between an ATIP synchronization signal and an encoded subcode frame synchronization signal is smaller than a predetermined value, the reference write clock is the write clock used by the compact storage device.

摘要： A disk drive includes an information processor 15 for reading out or writing information from or to the disk drive, a disk drive unit 11 for driving a disk 10, an access unit 12 for reading out or writing information from or to the disk 10, and a controller 13 for controlling the disk drive unit 11, and a disk controller 14. The disk drive is driven at a set drive speed. Format identification information is acquired from information recorded on the disk 10, and drive-speed information for the disk drive, determined from the acquired format identification information, is transmitted to control the speed of the disk.
