Claims

[Scope of utility model registration request]

A front core consisting of one end of three magnetic rods fixed to each other via a gap spacer, a back core attached to the other end of the front core, and a magnetic rod wound around the central magnetic rod of the front core. Two sets of magnetic head bodies composed of the above-mentioned coils are brought into contact with one end of the front core through a shield plate, and both magnetic head bodies are assembled into a V-shape, and then installed in a case. In the magnetic head for a video tape recorder, the bank core storage portion of the case is provided with a recess having a predetermined depth so as to absorb centering errors when attaching the bank core to the front core. Features: Magnetic head for video tape recorders.
