Abstract

PURPOSE: To suppress a rise in temperature when a magnetic erase head is in use and also to improve its erasability by forming a front magnetic core, used combined with a back magnetic core, of stacked high and low-magnetism saturated materials and further by forming a magnetic gap of the above-mentioned high-magnetism saturated material.
CONSTITUTION: Magnetic core 1 is formed of back magnetic core 11 and front magnetic core 12; magnetic core 11 nearly in a channel shape is made of a low- magnetism saturated material (e.g., ferrite) and provided with erase coil 3, and front magnetic core 12 of compound structure nearly in an inverted-channel shape consists of laminations of member 12B of a magnetic material constituting magnetic core 11 and member 12A of another magnetic material (e.g., Permalloy, Sendust, etc.) highly saturated in terms of magnetism. On the tape slide surface side of magnetic core 12, high-magnetism saturated materials 12A and 12A are confronted with piece 4 of a high-magnetic-flux-density material between the both to form double magnetic gap 5.
