Interesting... 600rpm? Wow!
Didn't Seagate/Shugart dabble in 3.5 disk drives early on around 83 or
84'ish???

I have a couple of Amdisk drives, love the
little buggers, yeah the
whole 3" drives vs the 3.5"s was weird, its what sank the drives in the
long run as Sony really pushed those drive hard and of course Apple's
adoption of them into its Mac's in 84' then Atari and Amiga following in
85/86 with their systems using 3.5's and eventually IBM catching up in
87' with its PS/2 line.
The discussion of 3.5" floppies probably wouldn't be complete wtihout
mentioning HP. What follows is a case of IIRC.
Sony had originally brought the 3.5" drives out as 40 track 600 RPM
drives.(OAD-1). While impressive with their shorter latency, the 600 RPM
drive was not compatible with existing controllers. HP adopted the Sony
3.5" format but standardized on a 300 RPM 80 track drive.
