摘要:
A method for forming a transducing head first requires the deposition of a bottom shield, a bottom thick gap, a bottom thin gap, a sensor, a first flux guide, a top thin gap, a top thick gap, and a top shield. After each of the layers is deposited, an air bearing portion of both the top and bottom thick gaps is removed, such that a length of the air bearing portion of the top thick gap is substantially equal to a length of the air bearing portion of the bottom thick gap. Next, an air bearing shield is deposited over the air bearing surface, the air bearing shield being in contact with the top and bottom shields, the top and bottom thick gaps, the top and bottom thin gaps, and the flux guide. Finally, the air bearing surface of the transducing head is planarized, resulting in the top and bottom thin gaps and the first flux guide each being exposed at the air bearing surface.
