摘要： Apparatus for precisely machining the surface of a workpiece comprises a rotating plate with a flat, horizontal abrasive-laden surface against which the workpiece surface is forced by gravity. The workpiece is carried on the free end of an arm pivotably supported remote from the end of the arm carrying the workpiece. Loading of the workpiece work surface can be varied by shifting weights along the length of the arm or transverse to the length of the arm. The workpiece itself can comprise a bar on which several magnetic transducing heads have been deposited. Machining the workpiece surface to a preferred position accurately defines a dimension of choice, such as the throat height of these transducers.

摘要： An adaptive bending structure or insert for a lapping device is disclosed. In illustrated embodiments the bending structure provides a wider control width between bending nodes for imparting bending to a workpiece for lapping or longer beam length to increase stroke input at outer ends of the bending structure. In illustrated embodiments, outer bending fingers of the bending structure have a wider width than inner bending fingers to provide the wider control width of the adaptive bending structure. The wider bending fingers of the bending structure connect to actuator fingers of an actuator module to adapt the actuator module to provide an increased control width for controlling bow and curvature of the workpiece during the lapping process.

摘要： Disclosed herein is a hard disk drive slider having an extended three-dimensional air-bearing surface (ABS). The slider has an ABS and a back surface opposite the ABS, where at least a portion of the back surface defines a plane (i.e., if the back surface is substantially flat, the back surface itself defines the plane). Defined herein is an ABS function, which describes the characteristics of a portion of the ABS in a two-dimensional plane made by taking a cross-section of the slider perpendicular to the plane defined by the at least a portion of the back surface. The cross-section of the slider taken perpendicular to the plane has an ABS function that is a multi-valued function, which is defined herein as a relation for which, for at least one possible input value along the selected axis in the plane, the relation evaluates to two or more distinct nonzero values.
