ABSTRACT:
A servo head for magnetic tape is provided. The head includes a substantial planar head surface. The head includes a leading edge that is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge includes a rounded portion so as to form an air bearing between the head surface and the tape. The leading edge can include an abrupt change in slope at the leading edge. Alternatively, the leading edge can include a smooth transition.
