IBM Archives: 704 Data Processing System

A word or number stored in the magnetic core memory in this fashion was available for calculation in 12 millionths of a second. In addition to this high-speed memory, the 704 had a magnetic drum storage unit. The drum could be used for storage of parts of the program, intermediate results, rate tables, or other information.

History of Computer Memory - ThoughtCo

The drum was a metal cylinder coated with a recordable ferromagnetic material. The drum also had a row of read-write heads that wrote and then read the recorded data. Magnetic core memory (ferrite-core memory) is another early form of computer memory. Magnetic ceramic rings called cores, stored information using the polarity of a magnetic field.
