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.
Claims7
A method for manufacturing a holographic storage layer, comprising:
- forming a plurality of reflective layers on a plurality of strip-shaped photosensitive substances respectively;
- arranging the photosensitive substances in a parallel arrangement;
- filling a space between the reflective layers with an adhesive such that the reflective layers are adhered by the adhesive therebetween;
- and
- cutting the photosensitive substances, wherein the cutting the photosensitive substances is performed after filling the space with the adhesive, and a cutting direction and a lengthwise direction of the photosensitive substances provided in the bundle-shape configuration are orthogonal.
