Method and apparatus for controlling the rotation of a turntable

摘要

The present invention relates to a method and an apparatus for controlling the rotation of a turntable, in order to move a disk mounting portion selected among a plurality of disk mounting portions installed on the turntable to a pickup side by a key input signal of a user which includes rotating the turntable by supplying a driving voltage to a turntable driving motor, sensing a rotational velocity of the turntable and the extract output delay time Td of the driving voltage of the motor for stopping the pertinent disk mounting portion at a reproducing position on the basis of the sensed rotation velocity, and cutting off the driving voltage output of the turntable driving motor after confirming the approach of the pertinent disk mounting portion to a reproducing position and confirming the output delay time. Accordingly, the disk mounting portion selected by a user is accurately moved to a request position regardless of the rotational velocity variation or aging of parts due to the load quantity variation of the turntable.
