摘要： A bracket for a hard disc drive combining three separate functions, a ramp, a latch and a connector bracket into a single assembly. The bracket assembly, mounted with ramp and latch, secures and seals the electrical connector connecting the flexible printed circuit on the head side of the actuator. Traditionally, latches are on the coil side of the actuator. Moreover, the combination bracket improves manufacturability while reducing overall cost for the disc drive. The assembly can be purchased complete from a supplier.

摘要： This device and method provide a hard disc assembly (HDA) printed circuit board (PCB) with the input/output connector and read/write connector on the same end. This allows the printed circuit board for a hard disc assembly to be about 70% smaller and cheaper than the prior art. This device allows for higher data rates and less noise by allowing shorter signal lines between the read/write connector, the integrated circuits and the input/output connector.

摘要： An apparatus allowing for a slider for use in a disk drive is disclosed. An embodiment of the present invention may include a leading side, a trailing side, at least two main rails, a slider surface with an air bearing surface, and at least one trench substantially parallel to the width of the slider. The trench in the air bearing surface results in a lower compression length of the slider and allows for particles to be channeled off of the disk surface.

摘要： A loadbeam is locally stiffened by either, 1. the addition of strategically placed extra material to the loadbeam, 2. not removing material during the etching process to form the loadbeam, or 3. special forming, by crimping or bending, at specific sites on the beam. The use of local stiffening, when placed about the loadbeam dimple or between the dimple and flexure attachment points, with or without additional damping, can significantly improve the dynamical response of the loadbeam and eliminate vibrational modes of a slider mounted on the loadbeam during HDI interactions with disk surface asperities during disk drive operation.

摘要： The sensitivity of the fly height of a HDD (hard disk drive) recording head to temperature variations can be greatly reduced, eliminated or controlled in a manner to enhance HDD performance under various temperature conditions by affixing a thermal element to the HGA (head gimbals assembly) flexure. The thermal element in this invention is a deposited, patterned layer of DLC (diamond-like carbon) that has a coefficient of thermal expansion that is less than that of the stainless steel flexure. As a result of the placement of this thermal element on the flexure, the temperature-induced angular variations of PSA (pitch static attitude) can be made to compensate for temperature-induced changes in the slider crown curvature, thereby reducing or eliminating fly height variations due to temperature.

摘要： The overcoat of a slider (alumina) is recessed relative to the slider ABS by a non-abrasive CMP process sufficiently to prevent thermal protrusion of the overcoat during subsequent slider use in a hard disk drive. The CMP process involves the oscillatory and rotational compressional contact between the ABS surface of the slider and a polymerically pre-treated compliant pad that is sprayed by an aqueous alkali lubricating solution having a pH between about 9 and 10. The overcoat is thereby also softened by the lubricating solution and removed by the compressional contact and no use of abrasives is required.

摘要： Gimbal designs are provided that minimize adverse dynamic performance of a HDD suspension, particularly subsequent to head-disk-interface (HDI) interactions. The improvement of operational performance can be seen in graphical representations of the vibrational modes of a gimbal mounted slider subsequent to such HDI interactions. Each gimbal design includes a ramp limiter formed as two separated arms connected by one or two transverse bars and a routing of conducting traces that relieves stress and minimally contacts these bars.
