ABSTRACT:
An adjustable holder for mounting a magnetic head so that it can be adjusted for both lateral and angular deviation with respect to the center line of a recording track. The holder includes a carriage adapted to receive guide pins and a yoke carrying the magnetic head on a leg at one end. The yoke is attached to the carriage by a fastener which permits vertical and rotational displacement. The leg of the yoke includes three equally-spaced openings to receive rotational coupling elements, each of which includes a shank having an enlarged head at one end and a flange with a diametrical groove at the other end. The carriage has three fixed pins received within the grooves of respective coupling elements. The axes of the coupling elements define the corners of one equilateral triangle while the axes of the fixed pins define the corners of a similar but non-congruent equilateral triangle.
