摘要: The present invention provides a thin optical disc drive whose impact resistance performance is improved.An under cover 19 is provided with a collision evasion hole 21 at a position corresponding to an end of an optical head housing 25. Moreover, a bottom cover 4 is provided with an impact force buffering member 22 at a position corresponding to the collision evasion hole. When an impact force acts on an optical disc drive 1, the impact force to the optical head housing 25 is buffered by the structure. Consequently, it is possible to prevent the optical head 8 from being damaged, and it is possible to improve the reliability of the optical disc drive 1.

摘要: There is provided a disc drive by which the fluid loss of a disc is reduced and the electric power consumption of a spindle motor can be decreased. In the disc drive according to the present invention, a rotation load reducing member is provided between a top cover and the disc. The rotation load reducing member is movably supported by a clearance adjustment member. While the disc is rotating, the rotation load reducing member is moved in the direction approaching the disc. Thereby, the thickness of an air layer on the upper surface of the disc is decreased.

摘要: 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.

摘要: A disk drive device has a configuration in which one of stepped parts defined by a circular recess for guiding a disc, formed in a disc tray is substantially flush with the bottom surface of the circular recess even in an area beyond the outer peripheral part of a disc so that no air cavity part facing the outer peripheral side surface of the disc is induced around the disc. Thereby, it is possible to aim at lowering cavity noise caused by the air cavity during high speed rotation and fluid noise caused by turbulence.
