An optical disc apparatus includes a turntable. The turntable is first rotated at a low speed in response to turning on of a reproduce switch on the disc apparatus, and the balancer is, in turn, brought to rest at an optimal position for low speed rotation. When the balancer comes to rest, automatic adjustment is effected. When the automatic adjustment is ended, the turntable is decelerated in rotation to release the balancer from resting. When the rotation speed of the turntable reaches a speed at which the balancer is released from resting, the balancer becomes movable relative to the turntable. Thereafter the turntable is brought into high speed rotation to move the balancer to rest at an optimal position for high speed rotation.
