Optical disk drive and method of controlling spindle motor thereof

摘要

An optical disk drive and a method thereof for controlling an optical disk drive spindle motor to adaptively stop the rotation according to the varying level of a detected tracking error signal. The optical disk drive directs the operation of the spindle motor by controlling driving voltage values to be supplied to the spindle motor depending on the level of a tracking error signal which varies according to the RPM of the optical disk.
