摘要： A magnetic head for a tape player comprises a head tip having a recess and a center tip interposed in the recess via spacers, and a back core having an L-shaped core and a center core. The L-shaped core has a like recess and the front end of the center core is interposed in the recess of the L-shaped core without coming into contact with the L-shaped core, while the other ends of the L-shaped core and the center core are connected to each other. A winding is provided around the center core, while the head tip is fixedly attached to the front surface of the back core so as to constitute a magnetic circuit, thereby providing a narrow head tip width erase head, while erasure efficiency is maintained high.
