Abstract: The magnetic tape cartridge transport includes a belt capstan which is accessible through the front edge of the cartridge for receiving rotary motion from a drive roller which is coupled to an electric motor. The electric motor extends through a motor opening in the base plate of the transport. A tape drive assembly includes an attachment bracket which is secured to the motor about its center of gravity and which extends laterally therefrom. The attachment bracket includes three apertures through which three shoulder bolts extend. The three shoulder bolts are positioned in a generally triangular spaced relationship about the motor opening of the base plate and are secured to the lower portion of the base plate. A pair of pivot pins are disposed between the lower surface of the base plate and the attachment bracket to permit the attachment bracket to pivot the tape drive assembly in a plane lying perpendicular to the front edge of the cartridge.
