Abstract
An optical data storage and retrieval system that includes a phase change storage medium and dual energy sources. The phase change material may store information by undergoing a transformation from one structural state to another structural state through application of energy. The system is equipped with two energy sources, neither of which alone provides sufficient energy to effect the transformation. The combination of both energy sources, however, provides sufficient energy to induce the transformation needed to record information. The energy from either source may be optical, thermal, electromagnetic, mechanical or magnetic energy.
