Abstract
Abstract An image information registering/retrieving system comprises an optical disk (19) for registering image information and for registering retrieving data, a magnetic disk (28) for storing the retrieving data, and a control circuit (11, 20, 22, 23, 24, 25, 27) for controlling the registering and retrieving operations. When the magnetic disk 28 loses its function and is replaced by a new one, the retrieving data on the optical disk (19) is copied on the new magnetic disk.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
An image information registering/retrieving system characterized by comprising: a first information-storing medium (19) 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 (28) on which said plurality of retrieving data is stored; and means (11, 22, 23, 24, 25, 27) 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 (19) is copied onto another second information-storing medium when said second information-storing medium (28) loses its function and is replaced by said another second information-storing medium.
Claim 2
Dependent Claim
121 words
An image information registering/retrieving system characterized by comprising: a first information-storing medium (19) 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 (28) on which said plurality of retrieving data is stored; and means (11, 22, 23, 24, 25, 27) 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 (19) is copied onto another second information-storing medium when said second information-storing medium (28) loses its function and is replaced by said another second information-storing medium.
Claim 3
Dependent Claim
42 words
An image information registering/retrieving system according to claim 1, characterized in that 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 -saoring medium is a magnetic disk.
