PHASE-MODULATED OPTICAL DATA STORAGE

This abstract first appeared for US patent application 18958980 titled 'PHASE-MODULATED OPTICAL DATA STORAGE

Original Abstract Submitted

A method of writing data to a transparent substrate comprises forming a first voxel by focusing a first laser pulse on a first location in a transparent substrate; and forming a second voxel by focusing a second laser pulse on a second location in the transparent substrate. The first laser pulse and the second laser pulse have different amplitudes, resulting in the first and second voxels having different strengths. Also provided are a system useful for implementing the method; an optical data storage medium obtainable by the method; and a method of reading data from the optical data storage medium.
