Abstract:
A method for forming a protective overcoat onto a tape bearing surface of a tape head used for magnetic tape recording. In order to ensure optimal surface tension and liftoff properties of the ink mask, the tape bearing surface is treated with a first application of ethanol, followed by an application of polydimethylsiloxane, followed by a second application of ethanol. After this treatment an ink mask can be printed onto the tape bearing surface so as to form a mask having an opening over the location of the magnetic transducer. An etching can then be performed followed by the deposition of a protective coating such as alumina.
