ABSTRACT:
In fabricating the magnetic head, a first magnetic shield layer (S1) is fabricated upon a substrate base, followed by a thin first insulation layer (G1). A photoresist mask is fabricated upon the G1layer and electrical lead recesses are milled through the G1layer and into the S1layer. An insulation layer is deposited into the electrical lead recesses, followed by the fabrication of electrical leads within the recesses. The photoresist is removed and a magnetoresistive (MR) sensor is subsequently fabricated on top of the G1layer, such that portions of the MR sensor are fabricated on top of portions of the electrical leads. Hard bias elements are then fabricated at outboard edges of the MR sensor. A thin second insulation layer (G2) is fabricated on top of the MR sensor and hard bias elements, and a second magnetic shield layer (S2) is fabricated on top of the G2layer.
