摘要： A disk-based holographic storage media includes a disk (10) fabricated from a holographic storage media (16). A plurality of holographic storage regions (54) are defined within the storage media (16) such that pages of holographic data (11) can be stored therein in the form of an interference grating. A Read/Write head (32) is provided for containing the optics necessary to read information from the holographic storage region (54) and write information thereto. The Read/Write head (32) moves along the radial direction of the disk (10) with the disk (10) stepped by a motor (12) to discrete angular positions, comprising the address of the storage region (54) along with radial positioning of the Read/Write head (32). In one embodiment each of the storage regions (54) is diamond-shaped and oriented such that the apexes thereof are oriented along a common radial column line. Adjacent columns have the storage regions (54) disposed in alternating rows or tracks. This allows for a higher packing density. In another embodiment storage regions are aligned with one side parallel to the tangent of the associated arcuate row. In yet another embodiment a two-dimensional non-disk medium is accessed by x, y positioning of the head.

摘要： A holographic storage media for storing digital data in the form of an interference grating is provided which includes a plurality of slabs of photorefractive material (72) arranged in a stack, with one edge thereof comprising an incident face (74). A data beam (39) having data superimposed thereon and a reference beam (38) are input to the face (74) to record a holographic image of the data in one of the slabs (72). Each of the slabs has a plurality of adjacent storage regions formed therein. The data and reference beams are disposed in a plane perpendicular to both the face (74) and the side (75) of the slabs (72), such that the reference beam (38) is confined within the slab (72) for all angles of the reference beam (38).

摘要： A holographic storage media for storing digital data in the form of an interference grating is provided which includes a substrate (48) over which a perforated opaque structure (50) is disposed. The opaque structure (50) has wells (52) disposed therein. In the wells, a photopolymer material (54) is disposed to form data storage regions (54). This is covered by a capping layer (56). The wells (52) are chemically and/or optically isolated from each other.
