Abstract
PURPOSE: To improve reliability and frequency characteristics by composing a head of a chip core part made of a specific magnetic material, an intermediate core part of a ferrite, and a back core part and then by forming the intermediate core part in a specific shape.
CONSTITUTION: In a magnetic head where magnetic cores 11A and 11B corresponding to 1st and 2nd channels consists of chip core parts 12a and 12b forming a magnetic tape slide surface with operation gap (g) of Sendust, etc., intermediate core parts 13a and 13b made of a ferrite, and back core parts 14a and 14b, part 15 of core 13a is elongated larger than part 15 of core 13b and elongation parts 15 are connected to cores 14a and 14b. Between cores 12a and 12b, and cores 13a and 13b, shield plate 16 with non-magnetic plates 17 bonded to both its flanks is provided. The tape slide surface of window 21 of shield case 20 with tape guide 31 is made uniform in resistance to wear by non-magnetic mask core 24 made of a material nearly as hard as chip cores 12a and 12b, and masks 22 and 25, thereby improving its durability.
