Abstract: A data reader may be configured at least with a magnetic stack that has a first magnetic layer separated from a second magnetic layer by a non-magnetic spacer layer. The first magnetic layer may have an areal extent on an air bearing surface (ABS) that differs from the second magnetic layer while the second magnetic layer can be configured with a first plurality of linear sidewalls that are each angled with respect to a second plurality of linear sidewalls of the first magnetic layer.

Abstract: A data reader may be configured at least with a magnetic stack positioned on an air bearing surface (ABS) and contacting a spin depolarizing layer that is a minority spin current carrier. The spin depolarizing layer can have a thickness and spin diffusion length corresponding to a net zero spin polarization at an interface of the magnetic stack and spin depolarizing layer.

Abstract: A data storage device may be generally directed to a data transducing head capable of magnetoresistive data reading. Such a data transducing head may be configured with at least a trilayer reader that contacts and is biased by a coupling feature. The coupling feature may have a smaller extent from an air bearing surface (ABS) than the trilayer reader.

Abstract translation: 数据存储设备可以通常指向能够进行磁阻数据读取的数据传输头。 这样的数据传输头可以配置有至少三层读取器，其接触并被耦合特征偏置。 耦合特征可以比三层读取器具有比空气轴承表面（ABS）更小的程度。
