Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. The method of claim 1 , wherein at least one of the photosensitive substances is a bar made of one of an optical storage material and a photosensitive material. 3. The method of claim 1 , wherein at least one of the reflective layers is formed by coating reflective material. 4. The method of claim 1 , wherein at least one of the reflective layers is formed through vapor deposition of reflective material. 5. The method of claim 1 , wherein the photosensitive substances are arranged into an array. 6. The method of claim 5 , wherein a combination of the photosensitive substances becomes at least one sheet structure after the cutting. 7. The method of claim 6 , further comprising: burnishing the sheet structure.
