Abstract
An image information registering/retrieving system comprises an optical disk for registering image information and for registering retrieving data, a magnetic disk for storing the retrieving data, and a control circuit for controlling the registering and retrieving operations. When the magnetic disk loses its function and is replaced by a new one, the retrieving data on the optical disk is copied on the new magnetic disk.
