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.

The implementations disclosed herein allow for formation of a magnetoresistive (MR) sensor shield that shields against both down track and cross-track interference. The shield can be formed in a single deposition step. In one implementation of the disclosed technology, a tail portion of the shield is eliminated by including a non-magnetic material adjacent to opposite sides of a middle portion of the sensor stack.

Provided are devices for use in a magnetic tape head, a magnetic tape head, and methods for forming the same. A device includes a chiplet including at least one of a reader and a writer. The device also includes an electromagnetic interference (EMI) shield embedded in the chiplet. The EMI shield is configured to inhibit electromagnetic interference during operation of the at least one of the reader and the writer.

The present embodiments relate to a PMR write head with a trailing shield that comprises a FeCoNiM composition. The FeCoNiM composition can be formed via an electroplating process by adding Fe.sup.2+, Co.sup.2+, Ni.sup.2+ and a transition metal salt to an aqueous solution comprised of other additives in an electroplating cell that has an Ni or Co as the anode. The plated HD magnetic material as the trailing shield in a PMR writer can minimize a wide area track erasure (WATE). Further, a high moment high damping shield can lower bit error rate (BER) and increase aerial density capability (ADC) of the write head.
