摘要： A method for burnishing a slider in a disk drive in which the disk is rotated in the opposite or reverse direction from that used to develop the air-bearing and to read and write data is described. Rotating the disk in the reverse direction results in no air-bearing being formed and the slider being in contact with the disk surface. The burnishing removes material over the magnetic transducers in the slider which separate the transducers from the disk resulting in greater sensitivity. Optionally the stopping point for burnishing can be determined by monitoring measurable parameters such as the change in the MR resistance (MRR), i.e., ΔMRR/MRR until a selected range is achieved. The invention can be used to remove an overcoat from the air-bearing surface of the slider, remove protruding areas from the slider and to remove debris from the disk surface.
摘要翻译：描述了一种在盘驱动器中抛光滑块的方法，其中盘沿与用于显影空气轴承的方向相反或相反的方向旋转并且读取和写入数据。沿相反方向旋转盘片不会形成空气轴承，并且滑块与盘表面接触。抛光去除滑块上的磁换能器上的材料，其将换能器与盘分离，导致更大的灵敏度。可选地，抛光的停止点可以通过监测可测量的参数来确定，例如MR阻抗（MRR）的变化，即DeltaMRR / MRR，直到达到所选择的范围。本发明可用于从滑块的空气轴承表面去除外涂层，从滑块移除突出区域并从盘表面去除碎屑。

摘要： A hard disk drive utilizes hard disks that recover the historically unused read/write space or real estate located in the load/unload zone. Approximately one-half of the load/unload zone is recovered and available for reading and writing operations by forming a first or radially outermost read/write track beginning immediately adjacent to the inner radial edge of the load/unload zone and proceeding radially inward from there to the conventional location of first tracks in the prior art. In another version of the invention, almost the entire load/unload zone is recovered and available for reading and writing operations by aligning the first track with the center of the load/unload zone and proceeding radially inward from there as described above. Both of these versions make significant additional surface area on the disk available where, in the prior art, no data was stored, thereby increasing the efficiency and storage capacity of the hard disk drive.

摘要： A disk drive utilizes a slider that is designed to fly very high or well above the surface of the disk when loading onto the disk and until a reading or writing operation requires the head to go to a relatively low-flying position with respect to the disk. Thus, the slider has two or more altitudes at which it flies depending on the operating conditions of the disk drive. The different altitudes of the slider are achieved by adjusting three primary variables: the rotational speed of the disk, selecting the radial position of the slider/actuator arm, and by the gram load. Other factors that may be used to tune this performance include pitch static attitude, pitch stiffness, and air bearing surface design.
