ABSTRACT:
A deck is formed integrally on a front side of a drive chassis. As the drive chassis is moved upward, a disk is mounted on a turntable. The disk is rotated at high speed by a spindle motor, and an optical pick up is reciprocatingly moved along a guide rail and a guide shaft, and a lens holder is moved in focusing directions and tracking directions. Laser light is projected onto the disk through an objective lens so as to read information recorded on the disk. Vibration damping holes are respectively provided penetratingly in the deck substantially between a spindle motor fixing recessed groove of the deck and the guide rail and between the recessed groove and the guide shaft.
