Abstract

PURPOSE:To make a reproducing operation possible by constituting the main magnetic pole into a ring form and by providing a magnetic gap in the side facing a magnetic recording medium and by providing a means, which detects the signal magnetic flux from the magnetic recording medium, in a part of the main magnetic pole above. CONSTITUTION:In case of recording, when a signal current is flowed to exciting coil 2, a magnetic force line corresponding to the signal current is so generated that it may pass through end face 8' in the side of main magnetic pole 8 which is brought into contact with tape 6, and magnetic layer 4 of tape 6 is magnetized, and magnetization on edge part 16 is left as it is and is recorded. In case of reproducing, the main magnetic pole 8 side is operated as a normal ring magnetic head, and the signal magnetic flux from tape 6 is detected by magnetic gap 11 and is taken out from the terminal of reproducing side coil 12 as a signal voltage. If desired, a magnetic sensing element can be provided to detect the signal magnetic flux. By this constitution, it is possible to make a head only for reproducing needless.
