Microdata had a setup they used for packs, then later for writing servo 
platters for their Reflex winchester drives.

Similar to this system someone made a video of on youtube


The electronics, optics, lasers and control heads show up on ebay from 
time to time.  The microdata unit was actually a version which output 
control signals, rather than a measurement head like this video, so that 
their logic could step the positioner.

Write logic which was not part of the drive was used when it was in 
manufacturing mode to write the servo on the drive before shipment.

For testing there was a cleanroom setup for testing, usually when 
working on heads and evaluation of media.
