The D-37C computer memory consists of a rotating magnetic disk driven by a synchronous motor at 6000 rpm. Adjacent to the disk are two fixed head plates which house the read and write heads. The disk has a thin magnetic oxide coating on both sides for storing information.
The D-37C's storage mechanism involves a rotating magnetic disk powered by a synchronous motor at 6000 rpm, alongside two stationary head units for data input/output. The disk is coated with a thin layer of magnetic material on both sides for storing data.
