ABSTRACT:
A magnetic head for tape recorders and the like is manufactured with cores made of alloys of elements such as Al and Fe which have relatively large potential differences. In order to avoid the galvanic effect which may be produced by segregation and impurities in the alloys, a part of the tape sliding surface is made of an element such as Zn which is lower in galvanic potential than elements forming the cores, and that part of the tape sliding surface is made electrically conductive to the cores.
