ABSTRACT:
A swift deceleration method of a disk system and a circuit thereof such as an Optical Disk Driver, Compact Disk Player, CD-ROM and the like, which can quickly control a vibrating lens support when the optical pickup has been stopped, is disclosed, thus enabling the disk system to switch tracks faster. The method forces the transition of a deceleration circuit from an unlock state to a lock state when the feed motor is stopped, moves the optical pickup in a radial direction and controls the vibration of a lens support during stoppage of the optical pickup by operating the feed motor in a deceleration mode when the feed motor is in transition from the unlocked state to the locked state.
