It was invented in 1932 and used widely in computers of the 1950s and 1960s, often as the main memory of a computer. It differed from [[hard disk]]s by having a separate read/write head on each track of the medium.<br /> <br /> == Links ==<br /> * [[Wikipedia:Drum memory|Wikipedia article]]<br /> * [http://foldoc.org/The+Story+of+Mel The Story of Mel] (anecdote of early programming involving drum memory)</div>
