摘要:
In a multichannel magnetic head including a plurality of head chips secured at fixed intervals to one head base mounted on a rotating drum. Each head chip is arranged so that a center of the curvature of each head tip is positioned substantially on a straight line or an extension of the straight line connecting each head gap to tis rear gap, and each of the head chips is arranged so that the distance L between a crossing point on said straight line connecting each head gap to its rear gap and the head gap, and the radius D of the rotating drum satisfy the following relationship: ##EQU1##
