ABSTRACT:
An integral head module having read and write elements positioned in an alternating relationship. A first pole piece of the integrated head module is formed with recesses into which are positioned write coils of write elements in order to provide write gaps of a greater length than the gaps of the MR read elements which are positioned on non-recessed portions of the first pole piece. The second pole piece is then affixed to the first pole piece together with a required insulating layer in order to form gaps of a first and increased length for the write elements and of a second and shorter length for the MR read elements.
