Abstract
A holographic storage layer includes a reflective structure and photosensitive units. The reflective structure is a grid-shaped structure and includes cavities. The photosensitive units are disposed in the cavities, in which each of the photosensitive units is surrounded by the reflective structure. First openings and second openings are defined by the reflective structure, and the photosensitive units are exposed by the first openings and the second openings respectively.
Claims16
A holographic storage layer, comprising:
- a reflective structure, wherein the reflective structure is a grid-shaped structure and comprises a plurality of cavities;
- and
- a plurality of photosensitive units disposed in the cavities and made of an optical storage material, which is able to store data by interference and exposure to light and to allow light leaving therefrom to become diffracted light according to the data, wherein each of the photosensitive units is surrounded by the reflective structure, a plurality of first openings and a plurality of second openings are defined by the reflective structure, and the photosensitive units are exposed by the first openings and the second openings respectively.
A holographic disk, comprising:
- a first substrate;
- a second substrate;
- and
- a holographic storage layer disposed between the first substrate and the second substrate, comprising:
- a reflective structure, wherein the reflective structure is a grid-shaped structure and comprises a plurality of cavities;
- and
- a plurality of photosensitive units disposed in the cavities and made of an optical storage material, which is able to store data by interference and exposure to light and to allow light leaving therefrom to become diffracted light according to the data, wherein each of the photosensitive units is surrounded by the reflective structure, a plurality of first openings and a plurality of second openings are defined by the reflective structure, and the photosensitive units are exposed by the first openings and the second openings respectively.
