Abstract

PURPOSE:To eliminate effectively the noise of a magnetic head and thus obtain a high-quality reproduced signal, by providing a magnetic path at the core of a reproduction head to lead the magnetic flux to negate the feed-through magnetic flux. CONSTITUTION:The main core is formed by holding the gap component 14 between the I type core 11 and the C type core 12 of the reproduction head, and the auxiliary core 12 is provided on both side faces of the core 12. Then the winding 13 is applied by putting together both the core 12 and the center foot of the auxiliary core 15. As a result, the feed-through components phif1 and phif2 are synthesized with an opposite phase the each other within the windings 13, and the integrated magnetic flux phi becomes as phi=phiS+phif1-phif2. Here if phif1=phif2 is satisfied, phi=phiS is obtained. Thus the feed-through magnetic flux can be eliminated completely, and only the signal supplied from the tape can be extracted.
