Same for CDC.

Given the weird and wonderful storage devices that were developed in 
earlier days, calling a random-access (although it could be posited that 
tape can be random access) storage device a "disk" is just wrong in may 
cases.

Consider:

UNIVAC FASTRAND -- a movable-head jumbo drum.
IBM 2321 - Data celld drive
NCR CRAM - magnetic card

etc.

Even now, the use of SSD to describe a bunch of flash devices is 
wrong--the things aren't even round.
