Abstract: PURPOSE:To improve matching with an electric circuit by providing a primary coil wire through an insertion hole formed between a pair of magnetic core half bodies and a transformer part and constituting a magnetic gap between magnetic core half bodies. CONSTITUTION:Large current is passed in the primary coil wire 23 by the effect of the transformer part 1 when a secondary coil wire 15 is energized.

Magnetic metallic thin films 21 having a high magnetic permeability and high saturation magnetic flux density are used for the magnetic thin films forming the gap G in such a case. The films 21 constitute an annular magnetic circuit enclosing the insertion hole 20 and the size if the hole 20 is governed by the size of the coil wire 23 but the coil wire 23 is wound one turn only and, therefore, the size of the hole 20 is reduced and the magnetic circuit is miniaturized. As a result, this magnetic head is advantageous for dealing with high frequencies and the easier reading of magnetic information is made possible by the miniaturization of the magnetic circuit. An improvement in efficiency at the time of reproducing is resulted as well.
