ABSTRACT:
A bidirectional linear thin film tape head and drive are disclosed with a flat contour on a wear resistant ceramic substrate. At least one thin film transducer is provided on a side of the substrate, forming one edge to the flat transducing surface, and another edge is formed at the opposite side of the flat transducing surface. In one embodiment, both the transducer edge, with an alumina overcoat protecting the transducer, and the opposite edge of the flat transducing surface form outer tape path edges, and in another embodiment, the thin film transducer is protected by a ceramic closure that covers the thin film transducer and forms an extension to the flat transducing surface which provides an outer tape path edge. The edges remove the air entrained by the tape moving relative to the head in either direction to allow contact or near contact recording with the flat transducing surface.
