摘要： A magnetic read apparatus has an air-bearing surface (ABS) and includes a shield, a crystal decoupling structure on the shield and a read sensor on the crystal decoupling structure. The crystal decoupling structure includes at least one of a magnetic high crystalline temperature amorphous alloy layer and a combination of a high crystalline temperature amorphous layer and an amorphous magnetic layer. The high crystalline temperature amorphous layer has a crystalline temperature of at least three hundred degrees Celsius. The amorphous magnetic layer is amorphous as-deposited.

摘要： A method of forming a wrapped-around shielded perpendicular magnetic recording writer pole is disclosed. A structure comprising a leading shield layer and an intermediate layer disposed over the leading shield layer is provided, the intermediate layer comprising a pole material and a dielectric material. A trench is formed in the dielectric material. A non-magnetic layer in the trench is removed via an ion beam etching process. A seed layer is deposited in the trench and over the pole material. A magnetic material comprising a side shield layer is deposited on at least a portion of the seed layer.

摘要： A magnetic read apparatus has a media-facing surface (MFS) and includes a read sensor, a magnetic bias structure and an insulating layer. The read sensor has a side, a front occupying part of the MFS and a back. The read sensor includes a free layer, a pinned layer and a barrier layer between the free and pinned layers. The barrier layer has a barrier layer coefficient of thermal expansion. The magnetic bias structure is adjacent to the side of the free layer. The insulating layer includes first and second portions. The first portion of the insulating layer is between the read sensor side and the magnetic bias structure. The second portion of the insulating layer adjoins the read sensor back. The insulating layer has an insulating layer coefficient of thermal expansion that is at least ⅓ of and not more than 5/3 of the barrier layer coefficient of thermal expansion.
