Abstract
A multi-channel head includes a substrate, a plurality of write elements arranged in a track width direction above the substrate in a lamination direction, and a plurality of read elements arranged in the track width direction above the plurality of write elements in the lamination direction. At least one of the plurality of write elements is offset from the others in the lamination direction. All the plurality of read elements are located higher than an uppermost one of the plurality of write elements in the lamination direction.
Claims6
A multi-channel head comprising:
- a substrate;
- a plurality of write elements arranged in a track width direction above said substrate in a lamination direction;
- and
- a plurality of read elements arranged in a track width direction,
- wherein said plurality of read elements are aligned in a single line, and
- said plurality of write elements are aligned in two lines, that are next to said single line of said plurality of read elements, in a staggered manner to alternate between said two lines such that every other write element is aligned, and each line includes at least two write elements,
- said plurality of write elements include coils having two layers, and
- each pair of adjacent ends of said coils has an overlap area in said track width direction, wherein each of said two layers alternately overlap with each other as viewed in said lamination direction.
