摘要： The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.

摘要： A method of producing a slider wafer populated with electromagnetic components optically aligned with photonic elements for HAMR applications. Laser chips are transferred from a laser substrate wafer to the slider wafer by a massively parallel printing transfer process. After wafer bonding the laser chips to the slider wafer, the shape and optical alignment of the photonic elements are precisely aligned en masse by lithographic processing.

摘要： A perpendicular writer of the present invention comprises a main pole connected to two return poles and further includes one or more shorting shields thereby reducing erasure field on double layer perpendicular media. The perpendicular writer may include side shorting shields connecting the first and second return poles thereby modifying the crosstrack field gradient. Additionally, the perpendicular writer may include a top shorting shield modifying the downtrack gradient and may additionally include a bottom shorting shield for further reduction of erasure fields. The distance between the main pole and the shorting shields may be modified to customize the write field gradient.
