摘要: A reader includes a free layer and a side shield that biases the free layer. The side shield includes a main bias layer having a first magnetic moment value and a first magnetization direction. The side shield also includes a compensation bias layer having a second magnetic moment value that is less than the first magnetic moment value and a second magnetization direction that is opposite to the first magnetization direction.

摘要: Implementations disclosed herein provide for an apparatus, comprising a synthetic antiferromagnetic reader structure, wherein total moment of a pinned layer is substantially greater than total moment of a reference layer. In one implementation, the pinning strength of the pinned layer is substantially reduced.

摘要: An apparatus comprising a base shield, a sensor stack, and a base seed layer separating the base shield from the sensor stack. The base seed layer has a base coupled seed section that is coupled with the base shield, and a base uncoupled seed section that is uncoupled with the base shield, wherein the base uncoupled seed section covers a base window surrounding the sensor stack.
