Abstract: A magnetic element may be configured with at least a magnetic stack having first and second magnetically free layers that each has a predetermined stripe height from an air bearing surface (ABS). The first and second magnetically free layers can respectively be configured with first and second uniaxial anisotropies that are crossed in relation to the ABS and angled in response to the predetermined stripe height.

Abstract: A data reader may be configured with a tuned microstructure by initially cooling a substrate to a temperature of 100K or lower and subsequently depositing at least one layer of a data reader on the substrate while the substrate is maintained at the temperature. The tuned microstructure may consist of at least a grain size, grain size distribution, interface quality between multiple layers of the data reader, resistance-area product, and magnetoresistance.

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.
