Abstract: A data storage master disk and method of making a data storage master disk. The data storage disk master is for use in a data storage disk replication process. The data storage disk molding processes produces replica disks having a surface relief pattern with replica lands and replica grooves. The method includes providing a master substrate. The master substrate is at least partially covered with a layer of photosensitive material. A surface relief pattern having master lands and master grooves is recorded in the data storage disk master, including the steps of exposing and developing the photosensitive material. The exposing and developing of a specified thickness of photosensitive material is controlled to form master grooves extending down to a substrate interface between the master substrate and the layer of photosensitive material, such that the width of the master grooves at the substrate interface corresponds to a desired width of the replica lands.

Abstract: In one embodiment, a holographic data storage medium includes a substrate, a holographic recording material, and an optically detectable tracking pattern on the medium. The substrate may have first and second substrate portions. The holographic recording material may be a photopolymer, and the medium may have a sandwiched construction, where the holographic recording material is sandwiched between the first and second substrate portions. The optically detectable tracking pattern may be replicated on at least one of the substrate portions. Alternatively, the optically detectable tracking pattern may be recorded as a holographic grating in the holographic recording material. The tracking pattern may facilitate the ability to pinpoint the location of the holographic bit maps on the holographic medium to within a fraction of a micron.

Abstract: A radiographic image reader acquires electronic signals corresponding to a latent image of an object produced by radiation exposure of a photoreceptive medium within a cassette. The radiographic image reader comprises a light-tight enclosure with at least one access port for inserting and removing the cassette. A scanner subsystem is mounted within the light-tight enclosure for scanning the photoreceptive medium within the cassette to initiate the acquisition of the electronic signals representative of the latent image. A cassette registration and interface subsystem within the light-tight enclosure comprises an electronic interface structure for electronically connecting the photoreceptive medium within the cassette to an electronic component external of the cassette to obtain the electronic signals corresponding to the latent image.
