    Abstract: A heat‑assisted magnetic recording (HAMR) disk drive uses a semiconductor laser mounted on a slider to deliver light to a near-field transducer (NFT) via a waveguide located inside the slider. The waveguide includes a core and cladding material that is transparent to the laser light and surrounds the core. Layers of stray light absorption material are located inside the slider on opposite edges of the waveguide core in the same plane as the core and on opposite sides of the waveguide core in planes spaced from the plane of the core. Portions of the waveguide cladding material are located between the waveguide core and the stray light absorption layers. The stray light absorption layers absorb light that leaks into the cladding material and substantially reduces stray light reflected to the laser to prevent undesirable laser power fluctuation.

    Abstract: Examples of a load beam are described herein that include a lifter tab extending towards a distal end, a dustpan defined by a dustpan forming line at a proximal end and the lifter tab at a distal end and a first and second plurality of rail sections separated by a longitudinal axis. The first and second plurality rail sections including a rear rail, an intermediate rail, and a front rail. The rear rail extends from a proximal end of the load beam to the first intermediate rail, the intermediate rail extends from the first rear rail to the dustpan forming line, and the front rail extends from the dustpan forming line to a proximal end of the lifter tab.

    Abstract: A trace gimbal is described herein. In some embodiments, the trace gimbal includes outer struts including a front outrigger at a distal end of the trace gimbal and a rear outrigger at a proximal end of the trace gimbal. The front outrigger includes a distal front outrigger and a proximal front outrigger, and the rear outrigger includes a distal rear outrigger and a proximal rear outrigger. The trace gimbal further includes a middle strut extending in a width direction of the trace gimbal and adjoining the proximal front outrigger to the rear outrigger, and an inner strut connecting the middle strut to a slider tongue. The inner strut includes a slot, and the inner strut and the middle strut adjoin the outer gimbal struts to the slider tongue.

    Abstract: A flexure is described herein. The flexure includes a slider tongue with a proximal end and a distal end. The sliding tongue including a leading edge at the proximal end prone to contact an undersurface of a load beam attached to the flexure. The flexure also includes a magnetic read/write head slider attached to the slider tongue at the distal end, at least one PZT microactuator affixed to the slider tongue, between the proximal end and the distal end, and at least one dampening device at the leading edge of the slider tongue configured to reduce an impulse during a non-operational shock event and reduce stress on the at least one PZT microactuator.

    Abstract: Disclosed herein is an apparatus (100) that comprises an actuator arm (116) that is pivotably connectable to a pivot post (118) at a proximal end. The actuator arm (116) extends linearly along a first axis (B) from the proximal end to a distal end. The apparatus (100) also comprises a lift tab (112) that comprises an elongate member (402). The elongate member (402) comprises a proximal end (408), coupled to the distal end of the actuator arm, and a distal end (406). The elongate member (402) extends linearly along a second axis (A) from the proximal end (408) to the distal end (406). The second axis (A) intersects the first axis (B) to define an angle (204) between the first axis (B) and the second axis (A). The distal end (406) of the elongate member (402) is configured to engage an incline member (108) when the actuator arm (116) is in an unload position to lift the actuator arm (116).
