Abstract:
A disk drive system having a slide mechanism for displacing a relative position of an optical head portion to a disk-shaped recording medium in the radial direction of said recording medium so as to record or reproduce information in or from said recording medium, comprising:a slide servo means for receiving an error signal of said slide mechanism and generating a slide drive signal on the basis of the error signal, thereby driving said slide mechanism; and a drive releasing means for detecting a precursory phenomenon of making unstable operation of said slide mechanism based on the error signal, and stopping a driving operation of said slide mechanism by said slide servo means upon detection of the precursory phenomenon, wherein said drive releasing means starts again continuously the driving operation of said slide mechanism after allowing an inert movement of the slide mechanism thereof and after an elapse of a specific time since stoppage of the driving operation of said slide mechanism by said slide servo means.
