ABSTRACT:
A flexible band positioning device arranged to convert rotaty motion of an outout drum of a stepper motor to linear motion of a carriage supporting a read/write head. A flexible band is attached to the drum and is at least partially wrapped around it. The end portions of the band are each guided around a different idler roller and are attached to a support frame. The idler rollers are rotatably mounted on the carriage and upon wrapping and unwrapping of the band around the drum, caused by rotary movement of the drum, move the carriage linearly.
