no, carousel memory, ~1960 facit ecm 64, sweden

the carousel permits access to any of over five million stored decimals digits in an average of less than two seconds. it contains 64 small reels of 8-channel magnetic tape mounted in two concentric circles on a wheel. a given reel of tape is read by indexing the wheel so that the selected tape is at the bottom. a weight attached to the end of the tape drops down past an air gap read/write head to an unwinding bin. photoelectric sensors control start, stop, and rewind. a fully loaded carousel wheel can be replaced in about ten seconds.
