Flying-type composite magnetic head.

摘要

A flying-type composite magnetic head comprises a slider (11) made of a non-magnetic ceramic and having side rails (15, 16) extending longitudinally on both lateral sides of the head. A slit (12) extends longitudinally in one (15) of the side rails. A magnetic core (13) constituted by a pair of core pieces bonded to each other with glass is fixed in the slit (12). Opposing surfaces of the core pieces are in a trapezoidal shape, top flat portions of the opposing surfaces being parallel to each other. At least one of the opposing surfaces is formed with an Fe-A l -Si thin layer. A pair of the parallel top flat portions of the opposing surfaces constitute a magnetic gap of the magnetic core (13). The magnetic core (13) is fixed in the slit (12) with glass (14) filled on both sides of the magnetic core (13).
