摘要： A perpendicular magnetic recording disk has a graded-anisotropy recording layer (RL) formed of at least two ferromagnetically exchange coupled CoPtCr-oxide magnetic layers (MAG1 and MAG2) with two nucleation films (NF1 and NF2) between the magnetic layers. NF1 is a metal film, preferably Ru or a Ru-based alloy like RuCr, sputter deposited on MAG1 at low pressure to a thickness between about 0.1-1.5 nm. NF2 is a metal oxide film, preferably an oxide of Ta, sputter deposited on NF1 at high pressure to a thickness between about 0.2-1.0 nm. MAG2 is sputter deposited over NF2. NF1 and NF2 provide a significant reduction in average grain size in the RL from a graded-anisotropy RL without nucleation films between MAG1 and MAG2, while also assuring that MAG1 and MAG2 are strongly exchange coupled.

摘要： The embodiments of the present invention relate to a magnetic read head with pinned layers extending to the ABS of the read head and in contact with an antiferromagnetic layer that is recessed in relation to the ABS of the read head. The recessed antiferromagnetic layer may be disposed above or below the pinned layer structure and provides a pinning field to prevent amplitude flipping in head operation. In these embodiments of the present invention, the read gap of the sensor, that is the distance between the highly permeable, magnetically soft upper and lower shield layers at the ABS, is reduced by the thickness of the antiferromagnetic layer.

摘要： In a heat-assisted magnetic recording hard disk drive, one or more thermally conductive features are incorporated to assist with dissipation of heat from a laser module that comprises a laser and a submount. The submount may be coupled to the slider with solder covering a wider adhesive area for enhanced conduction of heat away from the laser module and to the slider, one or both of the submount and the laser may include a surface coating that increases the thermal radiation of the corresponding component, and/or one or both of the submount and the laser may include fins configured to transfer heat from the corresponding component. Further, a HAMR HGA may be configured such that the submount is coupled directly to the suspension flexure using a thermally conductive material, for conduction of heat away from the laser module and to the flexure.
