ABSTRACT:
A tape recording system is provided for coupling the angular velocities of a pair of roller guides disposed one on either side of a head assembly. In one embodiment, the roller guides each comprise cylindrical first and second surfaces wherein the first surfaces guide a tape over the head assembly. An idler bearing comprising a cylindrical ring having an inside diameter surface engages in rolling contact the second surfaces of the pair of roller guides, thereby coupling the angular velocities of the pair of roller guides. In another embodiment, an idler bearing comprises a roller having an outside diameter surface that engages the surfaces of a pair of roller guides on each side of the head to couple the angular velocities of the pair of roller guides.
