ABSTRACT:
A thin film "third axis" magnetic head is provided which is resistant to head wear which heads typically experience when operating in close proximity to a magnetic recording media. A relatively soft magnetic core is formed on the third axis surface of a hard insulative substrate. The magnetic core includes a gap region at the edge of the third axis surface. The gap region and a portion of the magnetic core adjacent the gap region are covered with a protective layer of hard material, such as diamond-like carbon (DLC). In this manner, a ruggedized sandwich-like head structure is formed including the hard substrate, the enclosed relatively soft magnetic core and the protective layer of hard DLC material.
