Pre-assisting microwave-assisted magnetic recording with spin-torque nano-oscillators

ActiveUS12597436B2Record information storageAssembling head elementsFilm planeMagnetization
The present embodiments relate to a pre-assisting microwave assisted magnetic recording (MAMR) (PA-MAMR) write-head structure where the STO is disposed within a leading shield (LS). The STO can be used to pump energy into the media before the writing process. The STO can also pre-excite the media and let the media oscillation damp over the time and then switch under the writer field. The present embodiments can be easier to increase the magnetic volume and magnetic moment of the free layer, while also achieving a greater oscillation frequency with magnetization oscillations around the axis in the film plane.

Suspension flexure forming for gimbaling clearance

ActiveUS12592250B2Manufacture head surfaceRecord information storageHard disc driveClassical mechanics
A suspension assembly for a hard disk drive includes a load beam coupled with a corresponding flexure via a centerline weld at a distal portion of the flexure, where the flexure further includes a gimbal portion at least in part formed away from the load beam in proximity to the centerline weld. The gimbal portion may be formed away from the load beam by way of mechanical forming prior to welding to the load beam and / or at least lateral portions may be formed away from the load beam by way of laser irradiation to the flexure subsequent to welding to the load beam. In either case, clearance between the pivoting gimbal flexure and the corresponding load beam around the vicinity of the centerline weld attachment point is enabled, to provide freedom from interference between the parts and stable resonance modes throughout the media load z-height variations.
