摘要： 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 (180) is formed on the third axis surface (10C) of a hard insulative substrate (10). The magnetic core (180) includes a gap region (160) at the edge of the third axis surface (10C). The gap region (160) and a portion of the magnetic core adjacent the gap region (160) are covered with a protective layer (210) of hard material, such as diamond-like carbon (DLC). In this manner, a ruggedized sandwich-like head structure is formed including the hard substrate (10), the enclosed relatively soft magnetic core (180) and the protective layer (210) of hard DLC material.

摘要： A thin film helical conductor coil assembly (110) includes an electrically-nonconducting ceramic substrate (204) having a substantially planar surface and separated first and second magnetic elements (112,116) which mutually bound a volume of the ceramic substrate (204). The thin film conductor coil assembly also includes a thin film magnetic core (256), which magnetically connects the first magnetic element to the second magnetic element. The thin film magnetic core(256), which overlies the substantially planar surface of the ceramic substrate (204), is constructed from a compliant electroplated magnetic material. The thin film conductor coil assembly further includes an electroplated thin film helical coil (210) which traverses about the thin film magnetic core (256) and forms a conductive path from a first terminal (264) to a second terminal (264).
