Abstract
A magnetic head in one embodiment includes a first outer array of writers; a second outer array of writers; a first inner array of writers positioned between the first and second outer arrays; a second inner array of writers positioned between the first inner array and the second outer array; and an array of readers, at least some of the readers being generally aligned with the writers of the first and second outer arrays in a direction of media travel relative thereto, wherein the writers of the first inner array are misaligned with the writers of the first outer array relative to the direction of media travel.
Claims19
An apparatus, comprising:
- a first outer array of writers;
- a second outer array of writers;
- a first inner array of writers positioned between the first and second outer arrays;
- a second inner array of writers positioned between the first inner array and the second outer array;
- and
- an array of readers, at least some of the readers being generally aligned with the writers of the first and second outer arrays in a direction of media travel relative thereto,
- wherein the writers of the first inner array are misaligned with the writers of the first outer array relative to the direction of media travel,
- wherein the number of writers in the first outer array of writers is one half the number of readers in the array of readers.
A magnetic head, comprising:
- a first outer array of writers;
- a second outer array of writers;
- a first inner array of writers extending along a planar first tape bearing surface and positioned between the first and second outer arrays;
- a second inner array of writers extending along a planar second tape bearing surface and positioned between the first inner array and the second outer array;
- and
- an array of readers extending along a planar third tape bearing surface, at least some of the readers being generally aligned with the writers of the first and second outer arrays in a direction of media travel relative thereto,
- wherein the writers of the first inner array are misaligned with the writers of the first outer array relative to the direction of media travel,
- wherein the first, second and third tape bearing surfaces lie along offset planes.
