Abstract： |
The invented optical storage media of the disorder nano composite film as well as the application belongs to the optical memory technique area. The media includes the first interval layer, the second layer and the structural layer of the disorder nano composite film between the first and second layers. The composite film contains the following components: the insulator with good transparency of the semiconductor with the wide energy gap as well as any one or more kinds of metal, semi-metal or semiconductor with the volume fraction 0.3-0.7. The two components are random distributed. The invention also discloses the structure of the erasable and read only optical disc made from the said media. The media possesses the effects of light amplification and super diffraction resolution so as to realize the super high-density optical storage with the features of high thermal stability, good transmittance, etc. |
