摘要： A sub-ambient pressure, air bearing slider is disclosed for positioning a magnetic read/write head proximately to a rotating disk. The slider includes first and second rails extending along the side of the slider facing the rotating disk from a leading edge of the slider to a trailing edge of the slider. Each rail has a thigh region extending at an angle from the leading edge to a lateral side of the slider, a foot region extending at an angle from a lateral side of the slider toward the trailing edge of the slider, and a knee region at a lateral side of the slider coupled between the foot and thigh regions. Recesses are provided to shape the first and second rails. A central recess provides a volume for sub-ambient pressure. One or more tails can be placed within the central region to prevent the shifting of pressure completely to one side of the slider. The design of the first and second rails leads to a more uniform flying height for the slider and magnetic head over all tracks of the disk.

摘要： A disk drive is provided for flying at low flying heights, for example 2 1/2 mu ''. The disk drive includes an adhesive-bonded slider and head suspension design which does not lose its crown or camber with a change in temperature. In a preferred embodiment, the adhesive is applied at discrete points. It was found that applying the adhesive in this manner was sufficient to securely bond the slider to the flexure tongue and resulted in relatively little change in the crown or camber geometry over a wide range of temperatures.

摘要： A disk drive including firmware for overcoming stiction and breaking free the heads of a disk drive which may adhere to the disk surface when the disk is at rest. Upon start-up of the disk drive, if stiction at the head/disk interface occurs, the voltage to the spindle motor and/or actuator motor may be rapidly fluctuated so as to cause a pulsing of the spindle motor and/or actuator motor. Pulsing both the spindle motor and actuator motor creates forces in a plurality of radial directions to allow the head(s) to break free from the disk(s) in the direction of least resistance. Moreover, as the resonant frequency of the spindle motor varies depending on the number of heads that are stuck, the firmware pulses over a range of frequencies including the various resonant frequencies of the spindle motor corresponding to various numbers of heads stuck.

摘要： A disk drive, comprising a storage medium having data tracks for storing data, a spindle motor mounting the storage medium for rotation, an interactive element for reading information from and writing information on the data tracks of the storage medium and an actuator responsive to control signals, mounting the interactive element for motion to selectively position the interactive element relative to preselected data tracks of the storage medium and to move the interactive element from a first data track to a second data track in response to the control signals. The interactive element is arranged and configured to fly above the storage medium. Moreover, control electronics are coupled to the actuator for generating the control signals to cause the actuator to move the interactive element from the first data track to the second data track. The control signals include velocity control signals generated as a function of the number of data tracks to be crossed from the first data track to the second data track, and the location of the first data track relative to the second data track. The velocity control signals control the actuator to move at preselected velocities, including a maximum velocity.

摘要： A method is shown for testing a magnetic disk to be used in a disk drive. The method includes the steps of measuring a height profile of an outer radial edge of the disk (22), using the profile to determine a slope value for each of a pair of radial segments (54) of the disk, calculating a difference value between the slope values of the pair, comparing the difference value to a preselected threshold difference value and indicating when the difference value is equal to or less than the threshold difference value. The threshold value indicates an outer most diameter of the disk where fly height operation for a head (46, 48) is still stable.

摘要： A disk drive for flying at extremely low flying heights. The drive includes a disk clamp for clamping one or more disks within the disk drive, with the clamp exerting a substantially uniform pressure at the circular line of contact between the clamp and the disk. The disk clamp includes a raised circular wall around an outer radius of the clamp, which wall is formed as part of and integrally with the rest of the clamp. The wall serves to increase the structural rigidity of the clamp in a single axial section of the clamp, thereby providing a "stress barrier" to the transmission of localized stresses from the screw points. Thus, the pressure exerted by the clamp on the disk is evenly distributed around the entire clamp, and the distortion normally occurring at the inner diameter of the disk with conventional disk clamps is greatly reduced.
摘要翻译：用于在极低飞行高度飞行的磁盘驱动器。驱动器包括用于夹紧盘驱动器内的一个或多个盘的盘夹，夹具在夹具和盘之间的圆形接触线处施加基本均匀的压力。盘夹具包括围绕夹具的外半径的凸起的圆形壁，该壁形成为夹具的其余部分并与其一体形成。该壁用于在夹具的单个轴向部分中增加夹具的结构刚度，从而为来自螺钉点的局部应力的传递提供“应力阻挡”。因此，夹具在盘上施加的压力均匀分布在整个夹具周围，并且通常在具有常规盘夹的盘的内径处发生的变形大大降低。

摘要： A disk drive having a head and disk assembly designed to transfer data to and from the disk at very low flying heights, for example 2.5 mu '. Due to factors including shock, disk drive vibration and changes in ambient pressure, the head will occasionally fly below the average flying height during rotation of the disk. At these lower heights, the head may contact asperities protruding from the disk surface. The present invention operates with burnishable disks, such that, during operation of the disk drive and rotation of the storage disk, the repeated contact of the head slider with the higher asperities causes the asperities to be worn down, or burnished. In this way, each of the asperities on the disk surface are reduced to be below the flying height of the head when the head flies at lower than normal flying heights. Thus, the danger of damage to the head and/or disk due to intermittent contact of the head with the otherwise protruding asperities on the disk is removed.
摘要翻译：一种具有磁头和磁盘组件的磁盘驱动器，其设计用于以非常低的飞行高度将数据传送到磁盘，例如2.5微米。由于包括冲击，磁盘驱动器振动和环境压力变化在内的因素，磁头有时会在磁盘旋转期间飞行低于平均飞行高度。在这些较低的高度，头部可以接触从盘表面突出的凹凸。本发明使用可磨光盘操作，使得在磁盘驱动器的操作和存储盘的旋转期间，磁头滑块与较高凹凸的重复接触导致凹凸磨损或磨损。以这种方式，当头部飞行低于正常飞行高度时，盘表面上的每个凹凸减小到低于头部的飞行高度。因此，由于头部与其它突出的凹凸在盘上的间歇性接触而导致头部和/或盘损坏的危险被去除。
