CPC G11B 21/106 (2013.01) [G11B 5/012 (2013.01)] | 23 Claims |
1. A data storage device comprising:
a storage medium;
a read transducer, comprising:
a free layer configured to have a magnetization bias sensitive to an external magnetic field, wherein a direction of the magnetization bias forms an acute angle relative to a surface of the storage medium generating the external magnetic field; and
a pinned layer configured to have a fixed magnetization, wherein a direction of the fixed magnetization forms a substantially right angle with the magnetization bias of the free layer; and
a controller configured to cause the read transducer to:
target a readback location on a track boundary between adjacent tracks on the surface of the storage medium; and
generate a read signal indicative of perpendicular fields of the adjacent tracks and cross-track fields of the adjacent tracks.
