摘要： An air-bearing surface of a hard disk drive slider comprises a trailing edge wherein a magnetic transducer is coupled to the air-bearing surface. A leading edge is opposite from the trailing edge. A channel is coupled to the air-bearing surface wherein the channel comprises: a closure at a distal end proximal to the leading edge; a bottom surface; and a center of the channel approximately aligned colinear with a center of the magnetic transducer. In this configuration the channel generates significantly more negative pressure proximal to the leading edge thereby stiffening the air bearing during operation.

摘要： An air bearing surface (ABS) for a head assembly for a data storage device is described. The ABS includes a member, comprising a first extended region and a second extended region, wherein these two regions define a channel. This channel is open to the leading edge (LE) of the ABS, and is configured so as to allow air to flow along the channel toward the trailing edge (TE) of the ABS. As a result, the pressure of the air flowing along the channel does not experience significant fluctuations in pressure until approaching the trailing edge.

摘要： The present invention provides an optimized pad design for a slider that minimizes the effect of mask alignment tolerances to allow for a more consistent N58 pad area and hence a more controllable burnish rate of the protruding pad. The protruding pad includes a first portion and a second portion formed by processing material to form the first and second portion wherein at least a quantity of the first portion comprises a first material type and the second portion comprises a second material type, the protruding pad further comprising a boundary interface separating the first material type from the second material type, the boundary interface having a position on the first portion that is dependent upon an alignment tolerance for the processing and that defines a surface area for the material of the second type, wherein the surface area of the material of the second type is negligibly affected by the position of the boundary interface.

摘要： Disclosed is a negative pressure air bearing slider having at least one trailing edge pocket defined by a generally U-shaped rail open to the trailing edge of the slider, and at least one leading edge pocket defined by a generally U-shaped rail open to the leading edge of the slider. Also disclosed is a method for determining an optimal width for a leading edge pocket of predetermined length and depth to provide a flat fly height profile in combination with a trailing edge pocket of predetermined dimensions. For a given trailing edge pocket configuration, width optimization is achieved by constructing a number of prototype sliders, each having a unique leading to trailing edge pocket width ratio; measuring the inner and outer diameter fly heights for each prototype to obtain ID and OD fly height profile curves; and determining a leading edge pocket width corresponding to the point of intersection of the curves.
