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.
Claims7
A method of coupling the rotations of a pair of roller guides disposed one on each side of a head assembly, said roller guides supporting a tape moving across the head assembly, the method comprising:
- providing idler bearing means for simultaneously engaging in rolling contact a cylindrical surface of the idler bearing means with an outside diameter surface of each of the pair of roller guides;
- simultaneously engaging the cylindrical surface of the idler bearing means with the outside diameter surfaces of each of the pair of roller guides;
- providing a driving means for moving the tape linearly across the head assembly;
- and
- moving the tape across the head assembly to cause rotation of the pair of roller guides, said roller guides having the same angular velocity coupled to the angular velocity of the idler bearing.
A method of coupling the rotations of a pair of roller guides supporting a tape moving across the head assembly, the method comprising:
- providing a pair of roller guides disposed one on each side of the head assembly, said roller guides having first and second surfaces, said first surfaces supporting the tape moving across the head assembly;
