Claims

[Scope of Claim for Utility Model Registration] 1. In a magnetic head in which a shield plate is interposed between a pair of cores disposed within the magnetic head body, a grounding terminal portion is integrally formed on the shield plate and the grounding terminal portion is formed outside the magnetic head body. A magnetic head that protrudes from the top. 2. The magnetic head according to claim 1, wherein a printed circuit board for terminal connection is attached to the back surface of the magnetic head main body, and the grounding terminal portion of the shield plate is connected to the ground pattern of the printed circuit board.
