Composite magnetic head.

摘要

The head comprises a pair of magnetic core halves (10,10') each including a core block formed of an oxide magnetic material (1,1') and a soft magnetic thin film (3,3') disposed on said core block interposed with a reaction inhibiting layer (2,2'), said core halves abutting to each other so that a magnetic gap (G) is defined between the ends of said soft magnetic thin films (3,3'). The magnetic head has a size relation bcd/a </= 0.2 x 10<-><1><0> m<2> wherein a is a gap length, measured along the proceeding direction of a magnetic recording medium, c a gap depth, d a gap width as measured along the track width and b is a thickness of said reaction inhibiting layer (2,2'). Wavy (beat) noise of output signal due to the pseudo gap produced by the reaction inhibiting layer is effectively suppressed. <IMAGE>
