Abstract
A data storage system includes a high-power laser to form a laser beam at a first wavelength. A 2D patternable light valve having a phase change material responsive to a write beam at a second wavelength, and non-responsive at the first wavelength is used to pattern the laser beam.
Claims14
A data storage system, comprising:
- a high power laser able to form a laser beam at a first wavelength;
- a second laser able to form a write laser beam at a second wavelength;
- a 2D patternable light valve having a phase change material responsive to the write laser beam at the second wavelength, and non-responsive at the first wavelength.
A method of storing data, comprising:
- generating a laser beam at a first wavelength;
- using a second laser able to form a write laser beam at a second wavelength;
- and
- writing on a phase change material responsive to a write beam at a second wavelength, and non-responsive at the first wavelength, using the write laser beam from second laser to pattern a 2D patternable light valve.
