Abstract

PURPOSE:To enable vertical magnetizing recording and reproduction by using a primary winding and auxiliary winding under no evil influences of external noises, induction, etc. CONSTITUTION:A primary winding 4a is provided closely to magnetic recording medium 1 of auxiliary magnetic pole 3 with much interlinkage with magnetic flux generated by the residual magnetization of recording medium 1, and auxiliray winding 4b is arranged away from recording medium 1 with a little linkage with the magnetic flux. Voltages induced across the primary winding 4a and auxiliary winding 4b are amplified by amplifiers 5a and 5b; one output is put out of phase by level adjuster 6 and mixed with the other output and the mixture is outputted. External noises, when included, are canceled and the output containing no noise component can be obtained. For signal recording, the primary winding 4a is only driven.
