PURPOSE:To prevent the deterioration in the picture quality and interchangeability by pinching a main core of a 1st head chip by a reinforcement core and a reinforcement core plate and pinching the main core of a 2nd head chip by the reinforcement core and the reinforcement core plate pinching the main core of the 1st head chip. CONSTITUTION:The 1st and 2nd head chips 32, 33 are mounted on a head base 34 and the operating gap of the head chips 32, 33 has an azimuth angle of -alpha, +alpha respectively. The 1st head chip 32, at one end of the reinforcement core plate 37 made of a nonmagnetic material, is formed by bonding a spacer 38 whose thickness if (t) and using the same material as that of the reinforcement core plate 37, the main core 39 made of a Sendust and a reinforcement core 40 made of a nonmagnetic material while bonding them sequentially. Moreover, the 2nd chip 33 is formed by bonding the main core 41 made of a Sendust and the reinforcement core 42 made of a nonmagnetic material sequentially to the other end of the reinforcement core plate 37. The operating gaps 43, 44 of the 1st and 2nd head chips 32, 33 are deviated by the thickness (t) of the spacer 38. Furthermore, the thickness (t) is equal to the thickness (track pitch) of the main cores 39, 41. |
