Abstract
A thin film magnetic head includes a magnetic core formed by first and second magnetic layers with at least one winding of conductor layer provided therebetween. Separating layers are provided to electrically isolate the conductor layer from its neighboring layers. The separating layers are semiconductor layers.
Claims12
A thin film magnetic head comprising:
- first and second magnetic layers forming magnetic cores, said first and secod magnetic layers being magnetically connected at first ends thereof and forming a gap between second ends thereof;
- at least one conductor layer positioned between said first and second magnetic layers, said conductor layer comprising winding means through which current flows during use of the magnetic head;
- said at least one conductor layer having on each of two opposite sides thereof a separating layer means for separating and electrically isolating said conductor layer from adjacent layers;
- and
- said separating layer means on at least one side of said at least one conductor layer including a semiconductor layer.
