1 Terabyte 4th generation Optical Disk Storage    

Up to 20 layer low cost optical disc media technology needs only read / write head head modification

Overview

These inventions describe up to 20 layer low cost optical disc media technology which needs only read / write head modification for 1TB data or video storage on a single disk 20 times the data size and up to 2500 times faster read than Blu Ray.

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.

Primary Application of the Technology

Data back up, Hi-Resolution photo, HD Video, Games, personal entertainment storage etc.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

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
Subclass 112.23: Particular lens

Class 428: Stock Material Or Miscellaneous Articles

This is the residual class for: 1. Stock material in the form of a structurally defined web, sheet, rod, strand, fiber, filament, cell, flake, particle not provided elsewhere. 2. Stock material in the form of a web, sheet, mass or layer which consists of or contains a structurally defined constituent or element. 3. A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.
