Abstract
A fully manually adjustable embodiment has a base member fastened to and spaced from a tape deck frame. Two identical mounting block members are provided, one for a recording head and one for a reproducing head. A rear portion of each mounting block member is positioned in the space between the base member and the tape deck frame. Three balls, loosely retained in cylindrical bores in the bottom face of the base member, are seated in spherical recesses in the top face of each mounting block member. An adjusting screw, threadedly engaged with the base member, extends into each cylindrical bore, engaging the corresponding ball. Tension springs are connected between pins in the base member and each mounting block member to draw them toward one another and thereby engage the balls between the adjusting screws and the spherical recesses. Two of the balls on each mounting block member are located along a central axis of the head to establish an azimuth axis. The third ball is offset from the azimuth axis and establishes a zenith axis extending at right angles to the azimuth axis midway between the first two balls. The three adjustment screws for the three balls on each mounting block member provide optimum manual adjustment of azimuth and zenith; and they provide ready centering adjustment of the head relative to the tape. Another embodiment, for automatic motorized azimuth adjustment, substitutes a motor-driven universally pivotal connection for the third ball and its associated adjusting screw.
