Abstract
A system and method for providing a magnetoresistive head is disclosed. The method and system include providing a first gap and providing a seed layer. The seed layer is disposed above the first gap and has a space therein. The method and system further include providing a magnetoresistive element substantially covering the space in the seed layer and providing a hard bias layer above the seed layer. A portion of the hard bias layer is immediately adjacent to a portion of the magnetoresistive element.
Claims6
A magnetoresistive head comprising:
- a first gap,
- a seed layer having a space therein, the seed layer disposed above the first gap;
- a magnetoresistive element disposed substantially above the space in the seed layer;
- and
- a hard bias layer disposed above the seed layer, a portion of the hard bias layer being immediately adjacent to a portion of the magnetoresistive element;
- wherein the magnetoresistive element includes a top, a bottom and an edge, a first portion of the seed layer being sandwiched between a portion of the bottom of the magnetoresistive element and the first gap, a second portion of the seed layer not including the first portion of the seed layer being between the hard bias layer and the first gap, the portion of the hard bias layer being immediately adjacent to the edge of the magnetoresistive element.
