Anyone have any literature on the Vermont Research
5017?
It was a cartridge drive shipped from 1975 until 1985 probably rebadged and
sold under some system manufacturer's label.
I have Syquest drives, as well as
Jazz drives which both had embedded
servos. No literature on them at my fingertips.
Most likely the first HDD to
use embedded servo in a production drive.
First embedded servo drive I saw was a
Tulin 1/2 high 5 1/4" form
factor, 40mb RLL. Mine was still functional last time I fired it up.
It worked longer than a lot of other drives with servo tracks. They
largely died due to media (probably stuck) or servo problems though. I
think the Tulin and it's successors were plated media as well, rather
than oxide.
I am not sure that the difference is because of plated media vs. oxide,
anyone have a track record to discuss that?
