Claims

[Claims for Utility Model Registration] - (1) In a magnetic head having a pair of material pieces whose tips are formed in an arc shape, the curvature of the front part of the material piece in the direction of rotational entry, excluding the part near the brush tip, is such that the material piece 1. A magnetic head, characterized in that the curvature of the rear portion in the direction of rotational entry is different from that of the magnetic head. (2) The magnetic head according to claim 1, wherein the curvature of the front part of the material piece in the direction of rotational entry is larger than the curvature of the rear part of the material piece in the direction of rotational entry. (3) The magnetic head according to claim 1, wherein the curvature of the front portion of the material piece in the direction of rotational entry is substantially linear.
