摘要:
A method for protecting a thin film structure including fabricating a plurality of island structures in a recording gap of a magnetic recording head, exposing a substantial portion of the plurality of island structures by removing at least a portion of the surrounding recording gap material via at least one etching process, including ion milling, coating the magnetic recording head containing the plurality of island structures with a coating material, including silicon nitride or aluminum oxide, and removing at least a portion of the coating material via a removal process, including chemical-mechanical polishing or lapping, to expose an uppermost region of at least a portion of said plurality of island structures.
