ABSTRACT:
A phase-shift and tilt adjustable disk player includes a motor plate to which a spindle motor is fixed. An elastic attaching portion is provided for attaching the motor plate to a deck and simultaneously elastically biasing the motor plate toward the deck. Two adjusting screws are screw-threaded to the deck and each adjusting screw has an end portion which contacts a side portion from the bottom surface of the motor plate for lifting and lowering the motor plate from the deck at one side by a rotation thereof. A cam-shaped phase adjusting member is rotatably installed on the deck for moving the motor plate in a tangential direction of a disk. Therefore, a phase-shift and tilt of an optical pickup can be effectively adjusted by controlling the position and tilt of the spindle motor.
