This is the technique now used for making cassettes: a couple of weeks ago WEA announced that they had just invented it, but at least one manufacturer in the UK has been using for a year or so an Italian tape-copier (from Tapematic) that keeps the `master tape loop' in a 6 gigabit store made of (um) six thousand one megabit RAM chips. Pity they have to do the digital to analogue conversion before putting it on tape, I suppose. g
