Abstract

PURPOSE:To imporove characteristics such as video S/N, differential gain, differential phase, etc. by forming the magnetic head in the specific shape coverging toward gap part. CONSTITUTION:In the magnetic head comprising butting head cores 15, 16 respectively applied with windings 17, 18 and forming gap 19 and tape sliding face 22, its notch parts 23, 24 are formed to the shape wherein they buldge to the outer side than the straight line connecting the notch part edge 25 and track edge 26. By forming the notch parts in such a manner that their tapered faces become curves being convex to the outer side, saturating of portions other than the gap opposing faces before the gap opposing faces may be averted and recording which is superior particularly to magnetic tapes of high coercive force may by performed.
