ABSTRACT:
A tape head positioning system for a tape cartridge drive data backup system having a stepper motor with a lead screw connected to the stepper motor and a follower nut threadedly engaging the lead screw. The follower nut has a formed slot for receiving one end of a lever arm. The other end of the lever arm engages in a formed slot a head mounting assembly carrying the tape head and the lever arm is pivoted a first predetermined distance from the first end and a second predetermined distance from the second end. The ratio of the first predetermined distance to the second predetermined distance determines a mechanical advantage for the system thereby causing an inexpensive coarser motor to effectuate fine adjustments of the tape head.
