Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
109 words
An image information registering/retrieving system comprising: a first information-storing medium on which a plurality of image information and a plurality of retrieving data for reproducing said image information are registered, each of said retrieving data being in correspondence with the corresponding image information; a second information-storing medium on which said plurality of retrieving data is stored; and means for controlling said first information-storing medium and said second information-storing medium in such a manner that said plurality of retrieving data registered on said first information-storing medium is copied onto another second information-storing medium when said second information-storing medium loses its function and is replaced by said another second information-storing medium.
Claim 2
Dependent Claim
109 words
An image information registering/retrieving system comprising: a first information-storing medium on which a plurality of image information and a plurality of retrieving data for reproducing said image information are registered, each of said retrieving data being in correspondence with the corresponding image information; a second information-storing medium on which said plurality of retrieving data is stored; and means for controlling said first information-storing medium and said second information-storing medium in such a manner that said plurality of retrieving data registered on said first information-storing medium is copied onto another second information-storing medium when said second information-storing medium loses its function and is replaced by said another second information-storing medium.
Claim 3
Dependent Claim
39 words
An image information registering/retrieving system according to claim 1, wherein said first information-storing medium is an optical disk on which said information is registered by means of a laser beam, and said second information-storing medium is a magnetic disk.
