ABSTRACT:
A device or mechanism which converts rotary motion into linear motion. The mechanism is well adapted for converting rotary movement of a pulley which is driven by a stepper motor responsive to signals from a computer into linear motion of a magnetic head. The magnetic head is mounted on guides for linear movement with respect to a record. A flexible metal band is wrapped around and attached to the driven pulley, the ends of the band extending tangent to the pulley and parallel to each other, the ends being secured to the block or carriage carrying the magnetic head. Angular movement of the pulley tends to unwrap one end portion of the band and to wrap the other portion thereby moving the block carrying the head linearly.
