Abstract

Present two-sided head carriage designs are not amenable to automated head alignment due to the large friction loads which exist between the upper head arm and the carriage, and because of the disturbing effect of tightening mounting screws which mount the arm to the carriage. This carriage consists of a carriage assembly in which the upper head's load spring is isolated from the interface between the arm and the carriage base. The head load spring applies a force to the arm in the vicinity of the upper head, and yet the spring produces very little normal force at the arm-to-carriage interface. Because of this low normal force at the interface, the arm can be moved (to adjust the alignment of the upper head) without disturbing the carriage and the alignment of the lower head which is mounted on the carriage.
