摘要: A magnetic sensor includes a sensor stack having a first magnetic portion, a second magnetic portion, and a barrier layer between the first magnetic portion and the second magnetic portion. At least one of the first magnetic portion and the second magnetic portion includes a multilayer structure having a first magnetic layer having a positive magnetostriction adjacent to the barrier layer, a second magnetic layer, and an intermediate layer between the first magnetic layer and the second magnetic layer. The magnetic sensor has an MR ratio of at least about 80% when the magnetic sensor has a resistance-area (RA) product of about 1.0 Ω·μm2.

摘要: A perpendicular writer includes a surface, a main pole proximate the surface, a return pole proximate the surface, and a back yoke connecting the main pole to the return pole distal the surface. The return pole is configured such that a magnetization of a portion of the return pole adjacent the surface is held substantially parallel to the surface during a write operation.

摘要: A power supply reset boosting element which boosts a level of the reset voltage to a level higher than the level of the power supply. The boosted voltage is isolated from both the power supply and from undesired switching by special transistors which can withstand the voltage power supply level.
