ABSTRACT:
A magnetic transducing head is mounted on a transducing machine so that the angle of orientation (e.g., azimuth inclination) of the head with respect to the machine is adjustable as by means of a differential screw mechanism extending between two relatively pivotable portions of the mount. The screw mechanism comprises a manually-operable element having threads of two different pitches on the same axis, threaded respectively into the two mount portions. Thus the two mount portions are always held at an intended distance from each other without lost-motion play, and the sensitivity of orientation adjustment is increased, because the translation corresponding to unit angular movement of the screw is measured by the difference between the inverse-pitch dimensions of the two threads.
