Thin film magnetic head having increased core cross section

Claim 1

A thin film magnetic transducer comprising; a non-magnetic generally planar substrate, a first thin film magnetic core half formed on a first portion of said non-magnetic substrate, a second thin film magnetic core half formed on a second portion of said non-magnetic substrate adjacent said first core half to form a magnetic transducing gap between said first and second core halves at a surface of said head facing a travelling magnetic recording medium, said gap being elongated and extending transverse to the plane of the substrate, a coil wound around at least one of said first and second thin film magnetic core halves, said coil comprising a plurality of first coil portions underlying said one core half, a plurality of second coil portions overlying said one core half, and a plurality of third core portions connecting said first and said second coil portions to form said coil, said third coil portions being provided on said non-magnetic substrate at portions uncovered by said one core half; and a further core portion provided directly on and magnetically coupled to said first and second thin film magnetic core halves at a position remote from said magnetic gap.
