I recall the early 5 1/4" floppy drives used stepper motors for head positioning with a metal ribbon assembly. They had an aluminum drum attached to the stepper with a split metal ribbon wrapped around it whose ends were attached to the head assembly. It seems to me that a slightly upscaled system using larger metal strap and a larger drum (perhaps banding material) might be workable. One might even be able to incroperate the drive motor into the drum in some manner.

There are some sytems like this out there, this is one

If that is what you had in mind.
I used some on a hydraulic cylinder positioning application that worked out well.
