Abstract
In an indexing mechanism for advancing a transducer with respect to a rotated disk to record and/or play back information on the disk, the transducer is mounted on a cylindrical carrier having a flat surface along one of its sides. A fixed guide supports the carrier for longitudinal movement along a reference axis defining the direction of travel of the carrier relative to the rotated disk. The carrier is moved by a stepper motor which rotates a lead screw in threading engagement with the carrier. A pair of flat support surfaces of the guide contact the flat surface of the carrier along respective parallel lines arranged parallel to the reference axis. Another flat support surface of the guide contacts the cylindrical portion of the carrier along a line arranged parallel to the first two lines. Thus a three-point support is provided for the carrier which prevents it from being rolled about the reference axis as the lead screw is rotated to move the carrier along the axis.
