Abstract: A lateral spin valve reader and fabrication method thereof. The method includes forming an injector, a detector and a common channel layer that extends from the injector to the detector. The method also includes forming a first channel layer between the common channel layer and at least one of the injector or the detector with the first channel layer in contact with the common channel layer, thereby providing an interface between the first channel layer and the common channel layer.

Abstract: A lateral spin valve reader includes a detector located proximate to a bearing surface of the reader, a spin injector located away from the bearing surface, and a channel layer that substantially extends from the detector to the spin injector. The channel layer and the detector are substantially in a same plane.

Abstract: In accordance with one embodiment, a multi-reader can be manufactured so as to be able to read from multiple regions of a storage device contemporaneously during operation. Such a device can be configured, for example, by forming a first wall; forming a second wall; and utilizing the first wall and the second wall to form two adjacent reader stacks.

Abstract: Tolerances for manufacturing reader structures for transducer heads continue to grow smaller and storage density in corresponding storage media increases. Reader stop layers may be utilized during manufacturing of reader structures to protect various layers of the reader structure from recession and/or scratches while processing other non-protected layers of the reader structure. For example, the stop layer may have a very low polish rate during mechanical or chemical-mechanical polishing. Surrounding areas may be significantly polished while a structure protected by a stop layer with a very low polish rate is substantially unaffected. The stop layer may then be removed via etching, for example, after the mechanical or chemical-mechanical polishing is completed.
