ABSTRACT:
A magnetic head has a first magnetic core and a second magnetic core, a partition wall plate and sliders. The first and second magnetic cores are securely joined together through the partition wall plate in the widthwise direction of tracks of a recording medium. The sliders are disposed on the outer surfaces of the cores in the widthwise direction of the tracks. A surface of the partition wall that is opposite the recording medium is recessed from the sliding contact surfaces of the first and second magnetic cores and the sliders against the recording medium. This provides a concave groove which reduces the area of the sliding contact surface. Spacing loss by the magnetic head can be substantially extinguished and the wearing away of the recording medium can be avoided by air pressure produced in the concave groove.
