An approach to a head gimbal assembly (HGA), such as for a hard disk drive, includes a swage plate assembly coupling a suspension to one side of an actuator arm, where the swage plate assembly includes a baseplate having a through-hole and a swage boss insert comprising a flange and a swage boss extending from the flange through the baseplate through-hole. The HGA is configured such that the baseplate is positioned between the flange and the actuator arm, such that a distal surface of the flange is the surface closest to a corresponding recording medium, whereby the thickness of the suspension is effectively recessed within the material dimensional buildup of the other parts and a greater clearance is provided between the suspension and the recording medium.

The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a main pole, an EAMR stack disposed on the main pole, and a trailing shield disposed on the EAMR stack. The EAMR stack comprises a seed layer disposed on the main pole, a spin torque layer disposed on the seed layer, and a spacer layer disposed on the spin torque layer. At least one surface of the spacer layer in contact with the spin torque layer has a smaller or reduced area than the spin torque layer. The at least one surface of the spacer layer in contact with the spin torque layer is recessed from a media facing surface and has a smaller cross-track width than the spin torque layer and a smaller width in the stripe height direction than the spin torque layer.

A suspension is described. The suspension includes a base plate and a load beam coupled to the base plate. The base plate includes a distal elongated element and a proximal elongated element. The distal elongated element includes at least one non-straight baseplate edge and the proximal elongated element includes at least one non-straight baseplate edge. The load beam includes a first mounting shelf and a second mounting shelf. The load beam is coupled to the base plate such that the first mounting shelf is exposed adjacent to the distal elongated element, and the second mounting shelf is exposed adjacent to the proximal elongated element. The first and second mounting shelves are configured to receive an actuator, such that an edge of the actuator and the at least one non-straight baseplate edge forms a gap.

A suspension includes a load beam with first and second openings, a flexure including first and second outriggers, and first and second damper members. The first damper member is attached to the load beam and part of the first outrigger that overlaps the first opening of the load beam. The second damper member is attached to the load beam and part of the second outrigger that overlaps the second opening of the load beam. The first opening includes a region which is not covered by the first damper member, and the second opening includes a region which is not covered by the second damper member.

According to one embodiment, a suspension assembly includes a support plate including a distal end and a proximal end portion, a wiring member including a gimbal portion and provided on the support plate, and a magnetic head mounted on the gimbal portion. The gimbal portion includes a first end portion located on a side of the proximal end portion with respect to the magnetic head and welded to the support plate, a second end located on a side of the distal end portion with respect to the magnetic head and welded to the support plate, a tongue portion on which the magnetic head is mounted, located between the first end portion and the second end portion, and supported so as to be displaceable relative to the support plate, and a limiter opposing the tongue portion with a gap.

The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a first write head and a second write head each coupled to a first pad and a second pad of a slider pad and an electrical circuit coupled to the first and second pads. The first write head is a wide writing write head, and the second write head a narrow writing write head. The electrical circuit comprises a first sub-circuit and a second sub-circuit connected in parallel. The first sub-circuit comprises a capacitor and a connection to a first thermal fly height control (TFC) of the first write head. The second sub-circuit comprises an inductor and a connection to a second TFC of the second write head. The electrical circuit is further connected to a third TFC of a read head, the second write head comprising the read head.

A suspension includes a load beam, a flexure including first and second outriggers, and first and second damper members. The first outrigger is formed to oppose the first surface and across the first opening. The second outrigger is formed to oppose the first surface and across the second opening. The first damper member is attached to the first outrigger at the first opening and the first surface. The second damper member is attached to the second outrigger at the second opening and the first surface. An edge portion of the first opening and the first damper member are spaced apart and an edge portion of the second opening and the second damper member are spaced apart.

A magnetic tunneling junction (MTJ) structure is described. The MJT structure includes a stress modulating layer on a first electrode layer, where a material of the stress modulating layer is different from a material of the first electrode layer. The MJT structure further includes a MTJ material stack on the stress modulating layer. And the MJT structure further includes a second electrode layer on the MTJ material stack. The stress modulating layer reduces crystal growth defects and interfacial defects during annealing and improve the interface lattice epitaxy. This will improve device performance.

The present disclosure discloses an adhesive glue, curing method therefor, and application thereof. The adhesive glue comprises the following components in percentage by weight: 50% to 80% of a polyurethane-modified acrylate, 0.1% to 10% of a thixotropic agent, 0.2% to 8% of a thermal initiator, and 2% to 30% of a diluent, wherein the thixotropic agent is a carbon nanotube. The adhesive glue is soft and resilient; it has a high viscosity, good thixotropy, low curing temperature, and high curing degree. Silicon precipitation can be prevented because silicon is not a component of the adhesive glue. The adhesive glue has strong adhesion and meets the production and performance requirements of the HDD binding process. In addition, the adhesive glue can effectively prevent hard disk damage and scratching.

Examples of a load beam are provided. The load beam includes a base portion with an opening at a distal end. The opening is configured to receive a heat assisted magnetic recording (HAMR) head slider extending therethrough. The load beam also includes at least one load beam tab such that the load beam tab is further away from the base portion and a top surface of the HAMR head slider.
