A hard disk drive head slider is configured with a material void, such as a chamfer, positioned at a virtual intersection of a leading edge (LE) face and a suspension face. The material void provides for avoidance of structural interference between an actuator that is mechanically coupled with the slider and the suspension flexure during actuator operation, thereby enabling the actuator to achieve a full desired stroke.

A suspension board with circuit including a first mounting region for mounting a slider and a second mounting region for mounting a piezoelectric element. The wiring circuit board includes a metal support layer, a base insulating layer, and a conductive layer. The conductive layer includes a first wiring pattern, a second wiring pattern, and a shield wiring pattern. The first wiring pattern includes a read wiring. The second wiring pattern includes a power supply wiring disposed at spaced intervals to the read wiring. The shield wiring pattern includes a shield wiring disposed between the read wiring and the power supply wiring.

A magnetic tape recording module having electrical lapping guides located within and adjacent to an array of magnetic read/write elements. Electrical leads connected with the electrical lapping guides are buried deep within the head build, close to the substrate so that they can pass beneath the electrical leads of the read/write elements without any capacitive coupling between the electrical lapping guide leads and the read/write element leads. The presence of the electrical lapping guides within and adjacent to the read/write element leads provides much more accurate control of read/write element stripe height during lapping.

To control the resonance generated in the head assembly and improve property on the head location controlling. A head assembly includes: a slider having a head element; a slider supporting plate for holding the slider; a load beam for holding the slider supporting plate; a support projection which is arranged on the front end part of the load beam and on which the slider supporting plate is supported rotatably; a drive unit that rotates the slider supporting plate around the support projection; a dynamic vibration absorber arranged on the slider supporting plate, wherein the dynamic vibration absorber is disposed closer to the rear end side of the load beam than the support projection and has vibration freedom in the rotating direction of the slide supporting plate.

Described are magnetic recording heads that include an air-bearing surface and that are designed to be useful or potentially useful in two or more different types of fluid atmospheres; also described are related methods of testing the magnetic recording heads and installing the magnetic recording heads in a hard disk drive, as well as hard disk drives that contain a magnetic recording head as described.

A slider-mounted read/write transducer for a hard disk drive (HDD) has a topology that mitigates attraction and accumulation of lubricant and hydrocarbons during the HDD operation. The slider topology may include a pattern of cavities and channels symmetrically disposed about a central longitudinal axis. The slider may also have a transverse channel extending perpendicularly inward from an opening in each side edge of the slider to intersect a channel that extends longitudinally along a middle axis towards a leading-edge pad in which a read/write transducer is embedded. The ends of the transverse channel open into an air-carrying groove extending vertically upward in the side of the slider in which a side flow blocker (SFB) restricts the air flow into the channel portion.
