Class Information
Number: 369/100
Name: Dynamic information storage or retrieval > Specific detail of information handling portion of system > Radiation beam modification of or by storage medium
Description: Subject matter wherein the information signal is stored on or retrieved from the storage medium by a beam of radiant energy which is modulated by the information signal either (a) to store the information on a radiant energy sensitive storage medium, or (b) by a radiant energy controlling storage medium for subsequent retrieval by sensing of the radiant energy.
