Abstract
PURPOSE: To prevent an air pressure generated at a tape high-speed running time and obtain a head of a high contact property between a head face and a tape by forming an empty groove in the shield material interposed between cores for channel.
CONSTITUTION: In a multi-channel magnetic head where cores 1 with coil 2 wound around are laminated through shield material 3, where low-resistivity nonmagnetic materials 5 (for example, Cu and Al) are laminated on both faces at both edges of ferromagnetic material 4, and the edge face is polished into a head face, empty groove 6 is formed along shield material 3 placed on the head face. In respect to the magnetic head of this structure, the contact property between the head face and the tape is improved to obtain good and stable recording and reproducing operations even in case of high-speed tape running on the head face because positive and negative pressures are prevented in the tape flowing-in side and the tape flowing-out side.
