METHOD FOR ULTRA-DENSE DATA STORAGE VIA OPTICALLY-CONTROLLABLE PARAMAGNETIC CENTERS

摘要

A method for optically storing and retrieving information is provided that irradiates spin-defect centers in a substrate with red or blue light to change the charge state to form a pattern. This pattern encodes information and long-term data storage. The information is retrieved by irradiating the pattern with red light that causes the pattern to undergo fluorescence.
