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： An optical disc drive is fitted with a pickup, a non-contacting cooling plate, and a resinous movable spacer. The cooling plate adjacently faces and is fixed to the under, right, or left side of the pickup. The movable spacer is fitted to one of the facing sides of the pickup and cooling plate and prevents direct contact between the pickup and the plate. This drive structure prevents pickup movement interference due to collision between the pickup and the cooling plate, contamination production, needless electric conduction, etc., so that the clearance between the facing sides of the metallic pickup and metallic non-contacting cooling plate is narrow. The narrow clearance results in an improved heat conduction and radiation characteristic, improving the cooling of the whole pickup.

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.
