The drum is connected to a read-write head, which can detect and modify the magnetic data as the drum spins. The Magnetic Drum was one of the earliest forms of computer memory, and was used in many computers from the 1950s to the 1970s. The Magnetic Drum was also used as a secondary storage device for some applications.
