Abstract
An optical data recording method for a disk drive having a plurality of rotation speeds. First, a plurality of write strategies corresponding to different possible rotation speeds of the disk drive is provided. Next, the practical rotation speed of the disk drive is detected. Next, the write strategy is selected according to the detected rotation speed of the disk drive. Next, optical data is written to an optical disc with the selected write strategy. Finally, the practical rotation speed of the disk drive is continuously detected during writing of optical data, and optical data is written to the optical disc with different write strategy when the practical rotation speed of the disk drive is changed to correspond to different write strategy.
