.
That may be today's definition but if you check the literature of the 50's
and 60's I am sure u will find drums (along with Williams Tubes, etc)
categorized as random access devices. Even the first disk drive was the IBM
RAMAC 350 - as in Random Access Memory! I think IBM invented the term
Direct Access Storage in the 1960s to distinguish devices whose assess time
was short but variable; that is, in between core (random) and tape
(sequential).
So the historical definition may have been . needs essentially the same
time.
