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.

摘要： An optical disc apparatus includes, as a raising/lowering mechanism for moving a second base constituting a unit mechanism portion pivotally about a fulcrum so as to raise or lower the second base with respect to a first base as a base of the optical disc apparatus, a cam mechanism which is provided pivotably on the first base side within an orthographic projection area of the optical disc that is in a chucked state and which has a cam surface formed around and in the direction of a pivot shaft. In addition, a cam pin provided on the second base side is brought into engagement with the cam surface. When the optical disc inserted into the optical disc apparatus is chucked onto a turntable so as to be rotatable, the cam mechanism is pivoted about the pivot shaft by a cam drive section.

摘要： A brake system for a magnetic recording and reproducing apparatus especially suited to an apparatus wherein an operation mode is provided on both sides of a stop mode. A braking of the brake system can be released in the respective modes upon both sides of the stop position, and the braking can be instantly applied at the time of transfer from the fast-foward or rewind mode to the stop mode. The brake system includes a turning arm constructed so as to be extensible and contractable and operable both for an application and release of the braking in dependence upon whether the turning arm is turned in a contracted or extended state.
