Abstract
A magnetic head of the metal-in-gap type is provided with improved recording characteristics accomplished by increasing the thickness of the thin film layer(s) in a magnetic gap. This magnetic head has several thin film layers and an intermediate layer made of a non-magnetic metal, such as chrome or titanium, interposed between each adjacent thin film layer. The use of the intermediate layer results in the reduction of eddy current losses and film stress thereby improving the recording characteristics of the magnetic head.
