What do you mean by "a storage media"? Form where I sit CD's, DVD's, disk
packs and tapes are all storage media from which people have loaded
programs. I can agree only with the second half of your comment.
>(the IBM 650 did as "main memory" was really a drum, not core).
We normally cleared the drum before loading a new program; not something
that we would do if using it as a storage medium[1]. Further, when someone
shipped us a new version of a program they didn't ship us a drum, just
cards or tape.
[1] Besides, it was only big enough to hold the data from 250
cards.
