摘要： A loading/unloading mechanism for loading and unloading a magnetic head mounted on a magnetic disk drive for recording data in a magnetic recording medium. A suspension mechanism exerts a predetermined load on a flying head slider while the disk drive is not operated. A ramp mechanism supports the suspension mechanism and moves the head slider away from the surface of the medium. The whole or part of the ramp mechanism is constituted by an oscillation mechanism having a piezoelectric element. The static frictional force acting on the suspension mechanism and ramp mechanism is replaced with a dynamic frictional force to thereby reduce the friction. This saves power at the beginning of a loading operation and facilitates the control over the movement of the head slider caused by a positioner actuator.

摘要： A descaling abrading apparatus with abrading rolls comprises an apparatus frame, a bearing member, and a plurality of parallel abrading rolls supported horizontally by the bearing member. Each abrading roll includes a rotating shaft, disk-shaped abrading wheels successively mounted on the rotating shaft via their corresponding collars, and spring supporters each concurrently serving as a key and disposed between their corresponding abrading wheel and their corresponding rotating shaft. The abrading wheels of one abrading roll are each located facing the collar between two corresponding adjacent abrading wheels of another adjacent abrading roll. The bearing member is supported by the apparatus frame so that it may be vertically movable with respect to the apparatus frame and so that it may be vertically downwardly pressurizable by a pressurizing means.
