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.

摘要： Disclosed herein are hard disk drive sliders having one or more tunnels between the leading-edge surface of the slider and the air-bearing surface (ABS) that may be used to control the pitch and/or fly height of the slider. A slider comprises a leading-edge surface, an ABS, and a tunnel having an entry area at the leading-edge surface and an exit area at the ABS, the tunnel for directing gas impinging on the entry area through the slider and out the exit area toward a surface of a hard disk. The tunnel may be a convergent tunnel. The tunnel may include two or more branches.

摘要： Embodiments disclosed herein generally relate to a head slider within disk drive data storage devices. A head slider comprises a head body having a leading portion on a leading edge and a trailing portion on a trailing edge. The leading portion includes a first leading pad disposed at the MFS and a second leading pad disposed between the first leading pad and the leading edge. The second leading pad is recessed a first vertical distance from the MFS. One or more particle trapping holes are disposed between the first leading pad and the second leading pad. The one or more particle trapping holes are recessed a second vertical distance from the MFS, the second vertical distance being greater than the first vertical distance. Particles encountered by the leading portion may be suctioned into the one or more particle trapping holes, preventing the particles from building-up onto the MFS.

摘要： Embodiments disclosed herein generally relate to a head slider within disk drive data storage devices. A head slider comprises a head body having a leading edge, a trailing edge and an ABS. The ABS has a leading portion and a trailing portion, the trailing portion having a tail section disposed adjacent the trailing edge. The head body has three surfaces recessed from the ABS: a first surface disposed a first vertical distance, a second surface disposed a second vertical distance that is greater than the first vertical distance, and a third surface disposed a third vertical distance that is greater than the second vertical distance. A first plateau disposed at the third surface is bound between a second plateau at the first surface and a trailing pad of the tail section. Between the first plateau and the trailing pad are one or more notches disposed at the first surface.
