Embodiments of the present invention recite a write gap structure for a magnetic recording head. In one embodiment, the write gap structure comprises at least one layer of inert material is disposed proximate to the Ppole of a magnetic recording head. A layer of magnetic material is disposed between the layer of inert material and the Ppedestal (PP) of the magnetic recording head. In embodiments of the present invention, the write gap structure further comprises a second layer of inert material is disposed between the layer of magnetic material and the PP of the magnetic recording head. In embodiments of the present invention, the write gap structure only overlies a portion of the write gap of the magnetic recording head with reference to the throat height dimension of the write gap.

Laminated write gap to improve writer performance

Embodiments of the present invention recite a process for fabricating a write gap structure for a magnetic recording head. In one embodiment, at least one layer of inert material is deposited which is disposed proximate to the Ppole of a magnetic recording head. A layer of magnetic material is deposited which is disposed between the layer of inert material and the Ppedestal (PP) of the magnetic recording head. In embodiments of the present invention, a second layer of inert material is deposited which is disposed between the layer of magnetic material and the PP of the magnetic recording head. In embodiments of the present invention, the throat height of the write gap structure is defined wherein the layer of magnetic material and the inert layer only overlie a portion of the Ppedestal of the magnetic recording head.
