PURPOSE:To eliminate a spacing loss and to hold the output level in a high value for a long period at the running time by holding a head core consisting of a magnetic body between substrates consisting of wearproof materials on both sides and setting the radius of curvature in the chip thickness direction of a tape sliding face to <=1mm. CONSTITUTION:The head core 1 having a desired track width and consisting of a thin magnetic body is held between substrates 2 and 2' having the wear resistance to a magnetic tape on both sides, and the radius R of the curvature in the chip thickness direction of the tape sliding face is set to <=1mm. Thus, the head output is not degraded even if the tape is run for a long period, and the capacity is improve and the life is extended. |
