ABSTRACT:
A method of fabricating a magnetic transducer is described which uses a trailing shield throat pad to set the trailing shield throat height. The trailing shield throat pad is used as a part of the structural form over which the material for the trailing shield is formed. The trailing shield throat pad is preferably made of a material which can selectively be removed from the gap layer with a selective etching process such as reactive-ion etching (RIE). The front edge of the trailing shield throat pad is used to define a peninsula on the trailing shield and thereby the throat of the trailing shield.
