<p>The present invention relates to an optical storage medium (1) using nanoparticles (4, 5, 6), and more specifically to a multi-layer optical storage medium. According to the invention, the optical storage medium (1) has two or more storage layers (11, 12, 13, 21, 22) with nanoparticles (4, 5, 6), each storage layer (11, 12, 13, 21, 22) being made of a dielectric material, wherein the dielectric materials of at least two storage layers (11, 12, 13, 21, 22) have a different dielectric permittivity.</p> |
