Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
71 words
THE METHOD OF PROVIDING A PERMANENT RECORD AT HIGH SPEEDS COMPRISING PROVIDING A LIGHT SENSITIVE MEDIUM, MOVING SAID LIGHT SENSITIVE MEDIUM PAST A RECORDING HEAD AT A HIGH RATE OF SPEED, CAUSING ELECTRIC DISCHARGES WHICH PRODUCE SMALL POINT-LIKE LIGHT EMANATIONS OF SHORT TIME DURATION IN DIRECT PROXIMITY TO SAID LIGHT SENSITIVE MEDIUM THEREBY EXPANDING PORTIONS OF SAID LIGHT SENSITIVE MEDIUM TO ATTAIN CHARACTERS OF DESIRED CONFIGURATION COMPRISED OF SAID EXPOSED PORTIONS.
Claim 2

Claim 3
Dependent Claim
176 words
A RECORDER EMPLOYING AN ULTRA-MINIATURE LIGHT SOURCE COMPRISING IN COMBINATION A RECORDING HEAD AND MEANS TO MOVE A LIGHT SENSITIVE MEDIUM PAST THE RECORDING HEAD AT A HIGH RATE OF SPEED, SAID RECORDING HEAD INCLUDING A PLURALITY OF TRIGGER ELECTRODES AND AT LEAST ONE REFERENCE ELECTRODE, SAID ELECTRODE BEING POSITIONED ON THE SAME SIDE OF SAID MEDIA AND BEING ADAPTED TO CREATE LIGHT, SAID TRIGGER AND REFERENCE ELECTRODES BEING SEPARATED BY AN INTERPOSED DIELECTRIC LAYER HAVING A RELATIVELY HIGH DIELECTRIC STRENGTH WITH THE EXCEPTION OF CERTAIN EXPOSED SURFACES OF THE REFERENCE AND TRIGGER ELECTRODES WHICH ARE SEPARATED BY A DIELECTRIC MEDIUM HAVING A DIELECTRIC STRENGTH LOWER THAN SAID DIELECTRIC LAYER, SAID REFERENCE ELECTRODE BEING MAINTAINED AT A POTENTIAL FOR A TIME SUFFICIENT TO CREATE A PLURALITY OF SMALL DISCHARGES CREATING LIGHT EMANATIONS OF SHORT TIME DURATION BETWEEN SAID TRIGGER ELECTRODES AND SAID REFERENCE ELECTRODE ADJACENT SIAD EXPOSED SURFACES, SAID LIGHT EMANATIONS DIRECTLY EXPOSING PORTIONS OF SAID LIGHT SENSITIVE MEDIUM TO CREATE CHARACTERS OF DESIRED CONFIGURATION COMPRISED OF SAID EXPOSED PORTIONS AT A HIGH RATE OF SPEED.
