That description matches a number of 14" hard disks available at that
time. I still have a Shugart SA4000 (on a PERQ 1) which has a similar
design of HDA. But that one uses a synchronous mains motor to turn the
disks (and produces the write clock from a special head on one of the
disks, thus synchronising the whole thing to the disk rotation).
I have a couple of 14" Fujitsus (a massive 135MB apiece) similar to that.
They're the predecessors to the Eagles, which have heavy cast metal HDA
enclosures. Much more fun to watch (and listen to).
