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： A method, apparatus and program storage device for sensing increased resistance changes in an MR element to detect MR sensor events. The initial MR resistance for each slider is recorded during the drive build. The MR resistance is periodically monitored at later stages of the drive build and during normal operation. The later MR sensor resistance measurements are compared to the baseline measurement taken during the drive build to determine if an MR sensor event occurs, such as contact being made between the MR sensor and the recording medium or an MR sensor being positioned ON or OFF the ramp.

摘要： A method for measuring the clearance of a slider over a rotating disk by inducing a collision between the slider and the disk is described. After the normal flying height of the slider is established, the slider is driven into a collision with the rotating disk surface by applying a DC or AC voltage between the slider and the disk. The clearance data can be extracted from the induced collision by measuring a parameter, such as the change in the amplitude of the readback signal from the magnetic sensor, which is related to fly-height at the normal fly-height and at the disk surface. The two data points can then be used to derive the clearance. One embodiment uses a single beam interferometer to derive the vibrational displacement of the collision event.

摘要： A slider for magnetic data recording. The slider has an air bearing surface with a trailing edge pad that is configured with a series of recesses that damp slider oscillations during use. The series of recesses formed in the trailing pad of the slider reduce slider oscillations by creating localized pressure gradients within the generally high pressure area over the pad. The slider can be configured with a raised primary pad and a secondary raised pad formed on the primary raised pad. A series of recesses formed in the secondary pad prevent slider oscillations, which would otherwise be especially problematic in a slider having such a secondary raised pad and associated higher pressure area thereover.

摘要： A method for creating a hard drive includes installing a slider in a disk drive having at least one disk lubricated with a first stage lubricant. The slider is designed to be in contact with the disk at initial use. The slider is burnished. A second stage lubricant is added to the disk after the burnishing step. The first stage lubricant provides less lubrication than the second stage lubricant, allowing the slider to be burnished in a controllable manner during the burnishing step. The second stage lubricant then provides lubrication to the disk during use by the end consumer.
