Abstract
A magnetic head for use with a tape recorder or the like comprises a core having a gap and which has a non-magnetic material of a similar mechanical property as the core material bonded to the periphery or part thereof, thereby preventing a foul-up of the head surface with dusts and avoiding damage to the magnetic tape; the foul-up or the damage occurs when the periphery of the core is filled with a layer of synthetic resin adhesive.
