Claims

[Scope of utility model registration request]

A shield case, a shield plate attached to the front surface of the shield case and arranged in a direction perpendicular to the recording surface of the magnetic tape, and the shield plates are arranged so as to be inclined at the same mounting angle and symmetrical with each other through the shield plate. a pair of cores, a holder that holds the shield plate and the pair of cores, and a holder that is made of the same or comparable magnetic material as the shield case and is interposed between the holder and the inner wall of the shield case. A magnetic head consisting of a pressing member that presses the magnetic head.
