What removable disks are available for minicomputers?

[#Bill_Stewart]

I'm planning to put together a computer system based on removable disks.
The only disks I know about right now are the DEC RP06/RM05s, AT&T's
clone of the RM05 (which only works on the 3B20), and DEC's RA60.
Is there anything else out there with >=200 MB?  I'd like to consider
machines other than VAXen, and I'm not very impressed with the RA60.

		Thanks;  Bill Stewart
