Abstract

PURPOSE: To obtain the said head which can record and reproduce the high coercive magnetic tape efficiently, by clipping the plateshape center core between a pair of C type cores provided with windings, and providing the reproducing gap and the recording gap (formed wider than the reproducing gap) between the cores.
CONSTITUTION: The center core 12 of plate shape is clipped between the C type core 8 winding the recording winding 10 and the C type core 9 winding the reproducing winding 11, the reproducing gap 14 is formed between the cores 9 and 12, and the recording gap 13 (having 3W80 times the width of the said gap 14) is formed between the cores 9 and 12, and the recording gap 13 (having 3W80 times the width of the said gap 14) is formed between the cores 8 and 12, to constitute the magnetic recording and reproducing head. Further, by winding the reproducing cancelling winding so that the magnetic flux produced by the winding 11 can be cancelled, the reproducing signal erasing the low frequency noise signal produced with the leakage magnetic flux of the recording gap 13 can be obtained.
