摘要： An actuator supporting apparatus of a hard disk drive includes a pivot bearing including an inner ring, an outer ring, and a rolling member, which are installed coaxially, to support an actuator arm to pivot. The actuator supporting apparatus also includes a support structure to support upper and lower surfaces of the inner ring, and a buffer member interposed between at least one of the upper and lower surfaces of the inner ring and the support structure, to buffer vibrations and impacts. Thus, a feature of buffering vibrations and impacts by the buffer member is not changed and is constantly maintained, regardless of accumulation of manufacture allowance or a change in the environment. Also, a problem in reliability of a product due to deterioration of structural strength, which occurs in the conventional actuator supporting apparatus, does not occur in the actuator supporting apparatus of the present invention.

摘要： A disk drive comprises a cover plate with preload tension formed across the cover plate for increasing the stiffness of the cover plate. The preload tension is formed across the cover plate after the cover plate that was warped is secured to a base member of the disk drive to become un-warped. Such a cover plate with increased stiffness is not easily deformed and effectively minimizes propagation of noise generated from operation of the disk drive.

摘要： An actuator latch system of an HDD retains a swing arm in place when the magnetic head of the HDD is parked. The actuator latch system includes a rotatable latch lever that has a hook designed to absorb shock when the hook engages the swing arm. A rear end of the swing arm has a corner portion where first and second surfaces of the rear end of the swing arm meet at a point of inflection. The hook has a first portion, a second portion, and a third portion extending between and connecting the first and second portions. Inner surfaces of the first, second, and third portions delimit a slot. The inlet of the slot has a width that is less than a width of the corner portion. Thus, the inner surface of the first portion of the hook will contact the first surface of the rear end of the swing arm, and the inner surface of the second portion of the hook will contact the second surface of the rear end of the swing arm, when the HDD experiences a shock that cause the swing arm to rotate in one direction while the magnetic head is parked.

摘要： An end-tab extends from a suspension for an actuator within a data storage device such as a HDD (hard disk drive). A suspension body supports a read/write head, and the end-tab extends from the suspension body. At least one dimension, such as the width and/or the height, of the end-tab increases from toward a front end of the end-tab to toward the suspension body. Thus, the weight of the end-tab is minimized, and yet the stiffness of the end-tab is enhanced.
