ABSTRACT:
A magnetic head comprises first and second front core assemblies and a filler plate. The first front core assembly is connected to a back core to form a magnetic core such as a recording/reproduction core or an elimination core. The second front core assembly, which is arranged parallel to the first front core assembly, is connected to a back core to form a magnetic core such as an elimination core. Between the first and second core assemblies is arranged a filler plate having a shape which substantially corresponds to the combined shape of both front core assemblies superimposed one on another. The filler plate is made of a non-magnetic ferrite or ceramics.
