Patent for Sale:1 Terabyte 4th generation Optical Disk Storage
The technology comprises an optical disc positioning system, focused light source of 2 different wavelengths with longitudinal chromatic aberration; and sensors coupled to the stabilized focusing system through a spectrum splitter & controlled spectrum selector. The multilayer optical disk has alternating layers of optically transparent materials combined into groups incorporating a waveguide layer with a first refractive index lying between the insulating layer with a second refractive index and an information photochromic layer with a third refractive index.
Media samples have been manufactured and the read/write process is developed.
EU, KR, JP, CN, TW, SG, MY & ID patent counterparts are also available.

Class 369: Dynamic Information Storage Or Retrieval
Apparatus for the storage or retrieval of arbitrarily variable information which is retained in a storage medium by variation of a physical characteristic. The information is stored or retrieved by causing or sensing a variation of a physical characteristic of the storage medium by a transducer having relative motion along a continuous path.Subclass 44.14: Optical head servo system structure
