Abstract
A writer includes a leading edge, a trailing edge, a longitudinal axis defined between the leading and trailing edges, and a transverse axis orthogonal to the longitudinal axis. A writer region is provided at a protruded section of the trailing edge oriented along the longitudinal axis. A write pole is arranged at the protruded section to write data to two locations spaced apart from one another relative to the transverse axis for a range of skew angles.
Claims24
A writer, comprising:
- a leading edge, a trailing edge, a longitudinal axis defined between the leading and trailing edges, and a transverse axis orthogonal to the longitudinal axis;
- a writer region provided at a protruded section of the trailing edge oriented along the longitudinal axis;
- and
- a write pole arranged at the protruded section and configured to write data to two locations spaced apart from one another relative to the transverse axis for a range of skew angles.
1 more element
A transducer, comprising:
- a slider comprising an air bearing surface;
- a reader provided on the slider, at least a portion of the reader defined on the air bearing surface;
- and
- a writer provided on the slider, at least a portion of the writer defined on the air bearing surface and comprising:
- a leading edge, a trailing edge, a longitudinal axis defined between the leading and trailing edges, and a transverse axis orthogonal to the longitudinal axis;
- a writer region provided at a protruded section of the trailing edge along the longitudinal axis;
- and
- at least one write pole arranged at the protruded section and configured to write data to two locations spaced apart from one another relative to the transverse axis for a range of skew angles.
5 more elements
A method, comprising:
- moving a writer through a range of skew angles, a trailing edge of the writer comprising a protruded section with at least one write pole;
- and
- maintaining respective distances defined between the at least one write pole and each of two consecutively written longitudinally spaced locations, wherein the distances are substantially the same at each skew angle of the range of skew angles.
