ABSTRACT:
A complex magnetic head includes a center core made from a non-magnetic material, interposing a magnetic film between the center core and a recording and reproducing core at one side of the center core and another magnetic film between the center core and an erasing core at the other side of the center core, so as to alleviate a cross-feed phenomenum between the recording and reproducing core and the erasing core through the center core.
