Despite the source saying it is a 'disk' drive, I suspect its not. Apparently once upon a time, they actually had drum drives, which were meant to be short-term storage.
Sure looks more like a drum than a disk pack.
Then again, I could be wrong.
edit: It looks like I am! It does appear to be a disk drive.
