A magnetic head adjusting mechanism operable to adjust the position of magnetic heads with respect to a direction of a run of magnetic recording medium independently of the adjustments of the head gap angle, the heights of the heads and other adjustment items. The mechanism includes a head base plate carrying the magnetic heads and formed with a shaft bore in which is fitted a support shaft mounted on a chassis. The head base plate is resiliently biased about the axis of the support shaft. The rotation of the head base plate about the support shaft is limited by a tapered adjusting member formed by a tapered nut having a conical outer surface in contact with the head base plate and a screw shaft in threadable engagement with the tapered nut. The screw shaft is mounted on and extends from the chassis to support the tapered nut such that the generating line of the conical surface of the nut, which includes the point of contact of the nut with the head base plate, is substantially parallel to the axis of the support shaft. |
