摘要： A magnetic head slider including a central pad that is disposed at the trailing edge of the slider and designed to increase the flying height of the slider in response to heat induced protrusion of the head elements. The central pad of the present invention includes a body portion and two arm portions which project forwardly from a leading edge of the body portion, such that the leading portion of the central pad is formed with a generally U-shaped profile. The length of the arm members is preferably from approximately ¼ of the total length of the central pad to approximately ¾ of the total length of the central pad.

摘要： The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.
摘要翻译：改进的磁盘驱动器系统具有改进的致动器臂组件，其中臂独立且可单独地从致动器构件插入和移除。此外，每个臂单独地自锁到致动器构件中，而不需要诸如螺钉，弹簧和环之类的外部保持装置。由于臂可单独插入/拆卸，因此臂可以非常薄，从而允许头悬挂组件容易地附接到臂上，而不需要模锻，粘合，焊接或旋入。由于手臂可以非常薄，这大大降低了磁盘与磁盘的间距，因此大大降低了磁盘驱动器系统的整体高度。

摘要： A head gimbal assembly for disk drives is attached to an actuator arm using an adhesive. An etch pattern is formed in the mount plate of the head gimbal assembly, defining a mating surface area. An actuator arm is received by the mating surface area, the two members are suitably aligned, and an adhesive is introduced into the various channels that comprise the etch pattern through an access opening that is located outside of the mating surface area. By locating the access opening outside of the mating surface area, the adhesive may be introduced after a final alignment is achieved between the head gimbal assemblies and the actuator arms. Such manner of attachment may be used with individual actuator arms as well as when connecting head gimbal assemblies to an actuator comb assembly.

摘要： Magnetic head sliders having air-bearing surfaces designed to reduce the protrusion compensation effect. The magnetic head slider includes: at least one front pad located an upstream portion of the slider and operative to generate a lifting force; and a rear pad that is located downstream of the front pad and includes a load-carrying part, for generating a lifting force, and a head mounting part. The head mounting part is separated from the load-carrying part by a groove formed between the load-carrying part and the head mounting part. The head mounting part contains a heat source that generates heat energy and thereby causes a protrusion throw to form on the slider. The groove suppresses formation of the protrusion throw on the load-carrying part and thereby localizes the protrusion throw mostly in the area adjacent to the head mounting part.

摘要： A radially and axially preloaded bearing that has a very low mass and axial profile and which can be used in a actuator pivot of a direct access storage device without the need for a second bearing to counter the preload. An outer race of the bearing is split in order to form an open ring. Three balls are placed between the outer race and an inner race. Both the inner surface of the outer race and the outer surface of the inner race are formed such that two contact points exist between each ball and each race. Alternatively, the outer race is a closed toroid. The inner race is radially split to form a lower and an upper race, each being a closed toroid. In yet another alternative, the outer race is radially split into an upper outer race and a lower outer race. The inner race is a single closed toroid. A limiter is used to limit the movement of each of the balls. Alternatively, a conventional ball cage is used.

摘要： An air bearing design enables a slider to fly at a higher fly height when the rotational speed of the disk is reduced to about one-third of its operational velocity. In addition, the slider has a flat profile as it scans the disk surface at a low fly height sigma, and low fly height loss during track seek and high altitude operation. This design also provides write protrusion compensation and thereby mitigates spacing losses due to the write current swelling of the write element protrusion. The leading region of the rear pad of the air bearing is mildly concave. This design produces unexpected results by compressing incoming air flow in such a way that, even under two very different velocities, good air bearing lift is generated while compensating for write element protrusion.
摘要翻译：空气轴承设计使得当盘的旋转速度减小到其操作速度的大约三分之一时，滑块能够以更高的飞行高度飞行。此外，滑块具有平坦的轮廓，因为它以低飞高高度西格玛扫描盘表面，并且在追踪和高空操作期间具有低的飞高高度损失。该设计还提供写入突起补偿，从而减轻由于写入元件突起的写入电流膨胀引起的间隔损耗。空气轴承的后垫的前导区域是轻微的凹入。该设计通过压缩进入的空气流而产生意想不到的结果，使得即使在两个非常不同的速度下，也可以在补偿写入元件突出的同时产生良好的空气轴承升力。

摘要： A recording head for a disk drive with a load/unload mechanism has an air bearing on one surface. The air bearing comprises a patterned set of three air bearing pads, at least five shallow pockets and one deep pocket. A narrow gap extends from the deep pocket and separates leading ones of the air bearing pads and shallow pockets from each other. The air bearing pads have unique, step-shaped geometry and the rear pad is virtually free of any shallow area. This configuration gives the air bearing superior performance characteristics over prior art designs with load/unload mechanisms.

摘要： A glide head for burnishing or smoothing the surface of a magnetic disk has an air bearing on one side and a piezoelectric element on an opposite side. The air bearing comprises a patterned set of four or five air bearing surfaces (ABS) and etched pockets having multiple depths in the air bearing. The air bearing preferably has two front ABS, two middle ABS, and one rear ABS. This configuration gives the air bearing superior performance characteristics over prior art designs. When the glide head contacts a defect or asperity on the surface of the disk, the glide head vibrates and causes the piezoelectric element to become excited and emit a signal in response.

摘要： A method of manufacturing a transducer suspension system for a data storage disk drive device having electrical wires strung along the top surface of the suspension, by bending the wires around the distal end of the suspension and connecting the wires to electrical pads on the transducer slider below. The height of the wires is reduced by swiping the wires in a lateral direction using a two-finger member. The swipe operation bends the wires down to reduce the overall height and reduces the stress created by the wires in the electrical pad bonds and allows the slider gimbal the freedom to move.

摘要： A suspension system for disk drives is formed out of a multi-layer metal laminate. An etch-retardant layer is received between two outer metal layers at a pre-determined depth from the outer surfaces of the metal layers. Utilizing conventional photo-chemical etching process techniques, the etch retardant layer stops or retards the chemical etching at this pre-determined depth. In this manner, the inherent variably in etch rate is controlled, permitting the formation of finer geometries in the head suspension than would be otherwise possible.
