摘要： A self-loading disc head-slider has a slider body, with a leading slider edge and a trailing slider edge, and first and second raised rails. Each raised rail has a leading rail edge, inside and outside rail edges and a bearing surface. A cavity dam extends between the first and second raised rails. A subambient pressure cavity trails the cavity dam, between the first and second raised rails. A stepped leading taper extends from the leading slider edge to the bearing surfaces of the first and second raised rails. The stepped leading taper is formed of first and second steps. The first step is positioned along the leading slider edge. The second step wraps around the leading rail edges of the first and second raised rails and extends along a portion of the inside and outside rail edges of the first and second raised rails. The first and second steps have a step height of 0.05 to 1.5 microns.

摘要： A method and system for determining a shape of a portion of an air-bearing surface (ABS) of a head residing on a slider are described. The ABS is configured to fly at a fly height from and with a velocity with respect to a disk during normal operating conditions. The method and system include driving at least one heater residing in the head while the slider is substantially at the normal operating conditions with respect to the disk and the fly height. The shape of the portion of the ABS changes in response to the heater(s) being driven. The method and system also include performing Doppler measurements on the slider while the heater is driven. The shape may then be determined based on the Doppler measurements.

摘要： A head has a slider with an air bearing surface having a left trailing air flow dam extending from a trailing pad along a lateral axis, and a right trailing air flow dam extending from the trailing pad along the lateral axis in an opposing direction. A sub-ambient pressure cavity is disposed adjacent to and upstream of at least one of the trailing air flow dams. The trailing pad and the left and right trailing air flow dams together laterally span at least 75% of the width of the slider. Each of the left and right trailing air flow dams is recessed from the primary plane by a step depth in the range 0.05 to 0.5 microns, and the sub-ambient pressure cavity is recessed from the primary plane by a cavity depth in the range 0.8 to 2 microns.

摘要： A disc head slider supports a transducer relative to a data storage disc. The slider includes a slider body having a disc-facing surface with a leading slider edge, a trailing slider edge, and first and second slider corners at opposing ends of the trailing slider edge. First and second rails are disposed on the disc facing surface about a central recess and form first and second bearing surfaces, respectively. The central recess has a depth measured from the first and second bearing surfaces. First and second recessed surfaces are positioned between a trailing edge of the first and second rails and the first and second slider corners, respectively, and are generally coplanar with the central recess. Third and fourth recessed corner surfaces are positioned at the first and second slider corners, respectively, and are recessed from the first and second recessed surfaces.

摘要： A method of contouring a surface of a slider for supporting a transducer relative to a data storage medium includes applying a lithographic resist layer to the slider surface. The resist layer is then exposed through a single mask having 3a mask pattern defined by variation in an optical density through the mask. The resist layer is exposed in an exposure pattern corresponding to the mask pattern. Portions of the resist layer are removed as a function of the exposure pattern to produce a vertically contoured resist layer. The slider surface is etched through the vertically contoured resist layer during a single etching step to form a vertically contoured surface feature within the slider surface.
