ABSTRACT:
A magnetic head adjusting apparatus includes a base, an auxiliary base disposed over the base for supporting a magnetic head, and a first adjusting screw threadably engaged with the base to contact with its end face the surface of the auxiliary base which faces the base. The first adjusting screw moves in a direction perpendicular to the base to move the auxiliary base in the same direction, and engages the auxiliary base to support it so that the auxiliary base can rotate around the first adjusting screw axis. Second and third adjusting screws threadably engage the base at different positions to abut the surface of the auxiliary base which faces the base, and move in the direction perpendicular to the base to move the auxiliary base in the same direction. A rotating member is mounted for rotation relative to the base, and is coupled with the auxiliary base at a position offset from the axis of rotation of the rotating member relative to the base. Accordingly, the auxiliary base is rotated around the first adjusting member as the rotating member is correspondingly rotated, to adjust the magnetic head gap relative to a tape in a tape cassette next to the auxiliary base.
