				such as how close together data can be recorded. The Xerox
				LPS may use either 1600 bpi or 6250 bpi density magnetic media.
tape			drive	Input/output device that controls the movement of magnetic
				storage tape past the read/write head while data is accessed or
				stored.
			task	1. Any major job performed by a computer. 2. One of several
