ABSTRACT:
In an optical disk drive device, in order to reduce structural vibration noise and aerodynamic sound during high-speed revolution, a recess is formed at the deeper end. This recess is in a position axially symmetric to a hole for the movement of an optical head with respect to the axis of a spindle motor, and its size is substantially equal to that of the movement hole. This recess serves to suppress the vibration mode of a disk tray and the air flow between the disk and the disk tray. Noise is reduced even when the disk is turning at high speed.
