摘要： A composite magnetic head comprises a pair of magnetic core halves each including a core block formed of an oxide magnetic material and a soft magnetic thin film disposed on said core block interposed with a reaction inhibiting layer, said core halves abutting to each other so that a magnetic gap is defined between the ends of said soft magnetic thin films. The magnetic head has a size relation bcd/a.ltoreq.0.2.times.10.sup.-10 m.sup.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. Wavy (beat) noise of output signal due to the psuedo gap produced by the reaction inhibiting layer is effectively suppressed.
