Embodiment Construction

[0052] The following description is made for the purpose of illustrating the general principles of the invention and is not intended to limit the inventive concepts claimed herein. Furthermore, certain embodiments described herein can be used in combination with other described embodiments in various possible combinations and permutations.

[0053] figure 1 Several components of an exemplary hard disk drive 500 are shown in accordance with some embodiments. The magnetic hard disk drive 500 includes a spindle 515 that supports and rotates a magnetic disk 520 . The spindle 515 is rotated by a spindle motor (not shown), which is controlled by a motor controller (not shown), which may be implemented in the electronics of the hard disk drive 500 . A slider 525 supported by a suspension and actuator arm 530 has combined read and write heads 540 . Magnetic head 540 may include only one read sensor, or it may include multiple read sensors. The read sensors in head 540 may include,...

Abstract

Disclosed herein is a hard disk drive slider having an extended three-dimensional air-bearing surface (ABS), a method for making the slider, and a hard disk drive including the slider. The slider has an ABS and a back surface opposite the ABS, where at least a portion of the back surface defines a 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.
