Title:
MEDIA, SYSTEMS AND METHODS FOR OPTICAL DATA STORAGE
Document Type and Number:
WIPO Patent Application WO/2017/059782
Kind Code:
A1
Abstract:
Provided are media, systems and methods for optical data storage. A nanocomposite material for use as an optical data recording medium comprises nanoparticles embedded in a host matrix, wherein the host matrix comprises a material having a high structural stability, and the nanoparticles comprise optical functional components having a first physical or chemical state and a property of permanent transition to a second physical or chemical state upon exposure to corresponding optical radiation, whereby information may be recorded in the first and second physical or chemical states of the optical functional components over an extended time period.
