Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
122 words
A SYSTEM FOR HIGH DENSITY OR MEGACYCLE FREQUENCY RECORDING OF INFORMATION COMPRISING: A FILM SUBSTRATE HAVING MOUNTED THEREON A BLACK THIN THERMALLY VAPORIZABLE COATING HAVING A HIGHER FACTOR OF THERMO-OPTICAL ABSORBENCY THAN BOTH THERMO-OPTICAL REFLECTIVITY AND TRANSPARENCY, A SINGLE MODE LASER ADAPTED TO PROVIDE A SINGLE WAVELENGTH LASER BEAM, MEANS INTENSITY MODULATING SAID LASER IN RESPONSE TO PREDETERMINED INFORMATION, MEANS FOCUSING SAID LASER ON SAID COATING, MEANS MOVING SAID FILM PAST THE POINT OF IMPINGEMENT OF SAID LASER BEAM THEREON, SAID MODULATING MEANS LIMITING THE MAXIMUM INTENSITY OF SAID BEAM AT A POINT WHICH WILL CAUSE THE COATING TO BE REMOVED DUE TO THERMO-OPTICAL ENERGY ABSORPTION AND BELOW THE LEVEL WHICH WILL CAUSE DESTRUCTION OF SAID SUBSTRATE DUE TO THERMO-OPTICAL ABSORPTION THEREBY.
