no idea, but its called a hard drive. Core memory has nothing whatsoever to do with hard drives. Core memory is more analogous to RAM, but was made of small metal or ceramic rings through which wires were threaded. Applying voltages to the wires changed the magnetic polarity of the rings, allowing them to represent "on" and "off" states. See the Related Link for much more information.

Who invented a computer memory device?

I am not sure which device you are asking about, but one pioneer in the development of computer memory devices is the Chinese-American inventor An Wang. In the late 1940s, he invented the magnetic pulse controlling device; this discovery is important because it is the principle upon which magnetic core memory is based. Another important inventor was Jay Wright Forrester, who also made a major breakthrough in the late 1940s. Forrester invented the random-access magnetic core memory, still in use in most digital computers even today.
