ABSTRACT:
The magnetic head of the present invention has plural core members in abutting relation to form a magnetic circuit in which one of the core members is notched deeper than the other to suppress the saturation and leakage of magnetic flux, and in which one of the core members is notched deeper than the lateral end of the coil facing the magnetic tape and even with the approximate center of the coil to reduce the distortion.
