 A tape drive (or "transport" or "deck") uses one or more precisely controlled motors to wind the tape from one reel to the other, passing a read/write head as it does.A different type is the endless tape cartridge, which has a continuous loop of tape wound on a special reel that allows tape to be withdrawn from the center of the reel and then wrapped up around the edge, and therefore does not need to rewind to repeat.This type is similar to a cassette in that there is no take-up reel inside the tape drive.
