A multi-track read module including a hybrid thin film and mechanically closed shield includes a bottom shield layer onto which read elements are formed. A top shield is deposited over each read element. Each top shield is magnetically isolated from any other top shield and from the bottom shield layer. An insulative spacer layer is deposited between the plurality of top shields. A mechanical closure is affixed to the spacer layer.

A multitrack coupled element read head and a method for manufacturing such a read head are provided. The multitrack coupled element read head includes multiple coupled magnetoresistive read elements in a spaced relationship, and a support structure between a pair of coupled read elements, the support structure also being a magnetoresistive material. The read head also includes a closure material bonded on the plurality of coupled read elements and the support structure, where the support structure provides for substantially even pressure on the pair of coupled read elements such that shorting therein is eliminated.

Multitrack coupled element read head with support structure to eliminate

The present invention discloses an improved structure and method of forming a dual magnetoresistive element head. The dual magnetoresistive element head includes a first and a second magnetoresistive element and leads extending from opposite end segments of each magnetoresistive element. In one aspect of the present invention, the first and second magnetoresistive elements and the leads are simultaneously formed from a wafer comprising a first and a second magnetic layer separated by an intermediate gap layer.
