OPTIMIZED MEDIUM WITH ANISOTROPIC DIPOLE EMISSION FOR FLUORESCENT SINGLE OR MULTI LAYER STORAGE

摘要

Optical data storage method, reading method, device ( 40 ) and storage medium ( 42,43 ), comprising storing data by modifying optical properties of polymer material ( 42 ), whereby writing is initiated by reorientation of photo-orientable units, typically by illuminating with light at a wavelength that initiates the reorientation, and whereby reading of data includes collection of anisotropic emission from dipole emitters.
