Abstract
Apparatus for two dimensional data reading. In accordance with some embodiments, a magnetic read element has a plurality of read sensors positioned symmetrically about a pivot point with at least two of the read sensors configured to concurrently read two dimensional user data while being immune to skew angle misalignment.
Claims20
An apparatus comprising a plurality of read sensors positioned symmetrically about a pivot point, at least two read sensors of the plurality of read sensors configured to concurrently read two dimensional user data, each of the at least two read sensors having a common length and positioned approximately half the common length from the pivot point.
A magnetic read element comprising
- first and second read sensors positioned on opposite sides of a pivot point, each of the first and second read sensors having a first length;
- and
- a third read sensor positioned downtrack from and symmetric with the pivot point, the third read sensor having a second length greater than the first length.
A transducing head comprising:
- a slider configured to pivot about a pivot point and to be supported adjacent a data storage surface via an air bearing surface (ABS;
- first and second read sensors supported by the slider on opposite lateral sides of longitudinal centerline that intersects the pivot point;
- and
- a third read sensor supported by the slider at a downtrack position that intersects the longitudinal centerline, the third read sensor partially overlapping at least a selected one of the first or second read sensors.
