Patent ID: 7239478

Claim:
A write element for use in perpendicular recording in a data storage system, comprising: a first pole P 1 formed atop a read element; a first substrate layer formed over the first pole P 1 ; a second pole P 2 that defines a recess; a non-magnetic material that is deposited in the recess; a third pole P 3 that is deposited atop at least part of the second pole P 2 and the non-magnetic material; a shield gap that is deposited over substantially an entire surface of the third pole P 3 ; a magnetic buffer layer that is deposited over substantially an entire surface of the shield gap; the third pole P 3 having a top and a base, the base of the third pole P 3 being narrower than the top of the third pole P 3 ; a side gap formed alongside the third pole P 3 , the shield gap, and the magnetic buffer layer; and a shield layer that is deposited substantially over an magnetic buffer layer, the side gap, and the non-magnetic material.
