Baseplate resonant axis optimization

In one implementation, the presently disclosed technology teaches an apparatus with a head attached to an end of a baseplate. The baseplate includes a tilted section that causes a torsion axis of the baseplate to pass near the head. In another implementation, the presently disclosed technology teaches an apparatus with a load beam attached to a baseplate. The apparatus also includes a head attached to an opposite end of the load beam from the baseplate. The baseplate includes a mass-shifted section that causes a torsion axis of the apparatus to pass through the head. In yet another implementation, the presently disclosed technology teaches a method for reducing baseplate resonance amplitude. The method includes shifting a baseplate mass on a suspension toward an adjacent disc surface to move a baseplate torsion axis to pass near a head.

Alignment members

Example alignment members are provided herein. In one example, the alignment member includes a frame member, a stiffener member, a bracket member, and a spring member. The frame member includes a set of roller bushings. The stiffener member includes a set of cam members. The bracket member to receive the stiffener member. The spring member is connected to the stiffener member. The spring member to expand and contract based on the position of the set of roller bushings.

ABS design with soft bumper pads (SBP) for mitigating media damage and thermal erasure in hard disk drives (HDD)

A slider design for a hard disk drive (HDD) features an air-bearing surface (ABS) topography with soft bumper pads (SBP) formed proximally to corners of the leading edge and the trailing edge. The bumper pads are formed by a process that combines the use of a first photomask for subtractive etching of the ABS to form pedestals, followed by additive depositions onto the pedestals using a second lift-off photomask. The additive process deposits sequences of Si layers and diamond-like carbon (DLC) layers to produce a soft bumper pad that is energy absorbing and heat conducting, thereby protecting the recording media from surface damage and thermal erasures.
