ABSTRACT:
A thin-film magnetic recording head utilizing a timing based servo pattern is fabricated by sputtering a magnetically permeable thin film onto a substrate. A gap pattern, preferably a timing based pattern, is defined by the thin film. The gap pattern includes termination patterns or endpoints having one or more rounded corners.
