Abstract

PURPOSE: To enable an obtained magnetic head to provide recording and reproduction of high density by equipping a magnetic shielding member, made of a nonmagnetic metal material, on both sides of a magnetic recording medium parallel to a drive direction.
CONSTITUTION: On both sides of a conventional ring type head, for example, parallel to the driving direction (shown by the arrow) of magnetic recording medium 4, i.e. on both sides of core 2, platelike magnetic shielding members 51 and 52 made of a nonmagnetic metal material such as copper are arranged and fixed by an adhesive, etc. As a result, magnetic flux is shielded by members 51 and 52 in the head side direction, i.e. contiguous track direction, and consequently even if the track pitch is lessened, no leakage of magnetic flux to the contiguous track occurs, so that recording and reproduction of higher density will come into effect.
