ABSTRACT:
Apparatus for moving a transducer carriage intermittently along a tract relative to a recording medium employs belting arranged in a closed loop that is tensioned by engagement around at least one idler and connected to the carriage. Belt end segments comprising the loop are wrapped in opposite directions around the periphery of a stepping motor-driven capstan and their ends are secured thereto at axially spaced apart locations thereon. The belting and idlers are arranged so that all of the belt segments wrapped around the capstan remain parallel to the carriage track as the capstan rotates so as to advance the carriage a maximum number of increments along its track.
