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: A structure includes a channel waveguide and a pocket adjacent to an input facet of the channel waveguide. A laser having an output facet is positioned in the pocket. The structure includes a stop on either the laser or a wall of the pocket. The stop is positioned at an interface between the laser and the wall of the pocket such that the output facet of the laser and the input facet of the waveguide are separated by a gap.

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.
