Abstract: A read sensor that includes a free layer having a magnetization that changes according to an external magnetic field. The read sensor also includes an additional magnetic layer and a non-magnetic layer. The non-magnetic layer may include a corrugated surface facing the additional magnetic layer. The corrugated surface is configured to enhance uniaxial anisotropy in the read sensor.

Abstract: A data storage system may be configured at least with a seed lamination that is disposed between a magnetic stack and a magnetic shield. The seed lamination may be constructed and operated with a coupling buffer layer and a seed layer with the coupling buffer layer fabricated of an alloy of cobalt and a transition metal.

Abstract: Implementations disclosed herein allow a signal detected by a magnetoresistive (MR) sensor to be improved by providing for a region of reduced anisotropy within a synthetic antiferromagnetic (SAF) shield. The SAF shield includes first and second layers of ferromagnetic material separated by a coupling spacer layer. A distance between the first and second layers of ferromagnetic material is greater in a region proximal to the sensor stack than in a region away from the sensor stack.
Abstract translation: 通过在合成的反铁磁（SAF）屏蔽内提供减小各向异性的区域，可以改善由磁阻（MR）传感器检测到的信号。 SAF屏蔽包括由耦合间隔层隔开的第一和第二层铁磁材料层。 铁氧体材料的第一和第二层之间的距离在靠近传感器堆叠的区域中大于远离传感器堆叠的区域。

Abstract: A data sensor may be configured in accordance with some embodiments to have a magnetically responsive stack that contacts at least one shield. The at least one shield may be constructed with a non-rectangular shaped electrical contact, such as a triangular and trapezoidal shape, respectively positioned on top and bottom shields on opposite sides of the magnetically responsive stack.
