Title: Disk drive device, and method for calculating linear velocity
Inventor: YOSHIDA GOJI
IPC: G11B20/00
Filed: 2000-11-28
Abstract: PROBLEM TO BE SOLVED: To easily detect accurate linear velocity and to utilize the accurate linear velocity in accessing. SOLUTION: First absolute timing information is read at a prescribed position of a disk-shaped recording medium, track jump of the prescribed number of tracks is subsequently conducted, and second absolute timing information is read just after the track jump. Time from first absolute timing information read start timing to second absolute timing information read start timing is also measured. The reproduction required time of one cycle of a track is calculated in the vicinity of the prescribed position by using the respective first and second absolute timing information and the measured time, and the linear velocity of information recorded on the disk-shaped recording medium is further calculated from the reproduction required time for one track cycle and the value of a disk diameter at a corresponding track position.
