Abstract
Systems and methods for correcting read/write overlay errors in the manufacture of magnetic transducers for storage drives are provided. One such system includes a twisting tool configured to receive and secure a row bar having an elongated rectangular block shape and including a plurality of magnetic transducers spaced apart along a length of the row bar, and where the twisting tool is configured to twist the row bar at a plurality of areas along the length of the row bar.
Claims8
A system for correcting for overlay errors in row bars, the system comprising:
- a twisting tool comprising a force applicator, a first planar twisting segment, and a second planar twisting segment, wherein the first planar twisting segment and the second planar twisting segment are configured to receive and secure a row bar having an elongated rectangular block shape and comprising a plurality of magnetic transducers spaced apart along a length of the row bar,
- wherein the first planar twisting segment is proximal and the second planar twisting segment is distal relative to an end of the row bar;
- wherein the twisting tool is configured to twist the row bar about a longitudinal axis of the row bar at a plurality of areas along the length of the row bar, wherein the force applicator is configured to impart a rotational force on the first planar twisting segment and thereby cause the first planar twisting segment to impart a twisting force on the row bar sufficient to rotate a portion of the row bar about the longitudinal axis, and
- wherein the second planar twisting segment is configured to oppose the twisting force.
