PURPOSE:To suppress greatly the wear of a magnetic head which is produced on its sliding surface owing to the tape driving, by setting the direction of crystallization toward a place where a high output is secured for a core at the tape entrance side and a place having the wear resistance for a core at the tape exit side respectively. CONSTITUTION:The directions of crystallization of both cores 40 and 41 set at the tape entrance and exit sides centering on the tape driving direction 5 are set asymmettical to each other. For directions of crystallization with the core 40, a sliding surface 42, the driving direction, a side surface 43, a side surface 44 and an arrow head 45 are set at the -112 face, the -11-1 direction, the 1-11 face, the 110 face and the 00-1 direction respectively. While a sliding surface 46, the driving direction, a side surface 47, a side surface 48 and an arrow head 49 are set at the 110 face, the 00-1 direction, the 00-1 face, the 110 face and the -110 direction respectively with the core 41. This can reduce greatly the wear of the surface 46 of the core 41 having a large number of contacts with a tape and also improves the S/N. |
