An optical data storage system comprises a multiple data surface medium and optical head. The medium comprises a plurality of substrates separated by a light transmissive medium. Data surfaces are located on the substrate surfaces. A layer of a semiconductor material is deposited onto each of the data surfaces. The thickness of the semiconductor layer determines the amount of reflectivity for each of the data surfaces.
L'invention porte sur un système de stockage optique numérique qui comprend un support d'information à surfaces multiples et une tête optique. Le support comprend une pluralité de substrats séparés par un support à transmission de lumière. Les surfaces du support d'information sont placées sur les surfaces des substrats. Une couche de matériau semiconducteur est déposée sur chacune des surfaces du support d'information. L'épaisseur du semiconducteur détermine le niveau de réflectivité de chacune des surfaces.
