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 transducing assembly positioned across an air bearing surface (ABS) from a data medium having a plurality of data bit arranged in first and second data tracks each having a first length along a common axis, the transducing assembly comprising a pivot point on the ABS disposed between first, second, and third read sensors configured to concurrently read two dimensional user data, the first and second read sensors having a second length along the common axis that is less than the first length and the third read sensor having a third length along the common axis that is greater than the first length.
An apparatus comprising a transducing assembly positioned across an air bearing surface (ABS) from a data medium having a plurality of data bit arranged in first and second data tracks each having a first length along a common axis, the transducing assembly comprising a pivot point on the ABS disposed between first, second, and third read sensors configured to concurrently read two dimensional user data, the first and second read sensors having a second length along the common axis that is less than the first length and the third read sensor having a third length along the common axis greater than the first length, the first, second, and third read sensors positioned symmetrically about a longitudinal line extending through the pivot point orthogonal to the common axis and positioned asymmetrically along the common axis extending through the pivot point.
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), the data storage surface having first, second, and third data tracks each having a first length along a common axis;
- first and second read sensors supported by the slider on opposite lateral sides of a longitudinal centerline that intersects the pivot point, the first and second read sensors each having a second length along the common axis that is less than the first length;
- 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 to concurrently read two dimensional user data, the third read sensor having a third length along the common axis greater than the first length.
