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 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: The invention is directed to data cartridges including a plurality of data storage disks. The invention applies the multi-disk data cartridges to a “jukebox” system in which one of the data cartridges is inserted into a computing device that de-cartridges and positions the data storage disks on one or more disk drives for reading or recording. A multi-disk data cartridge may comprise a cartridge housing with dimensions that conform to a magnetic tape cartridge housing standard form factor. The data cartridges may include blue disk media, such as Blu-Ray and HD-DVD. In order to integrate blue disk media into the data cartridge described herein, the blue disk media may comprise dimensions that conform to a non-standard blue disk form factor. In other cases, a cartridge housing may conform to a non-standard form factor based on dimensions of a standard form factor blue disk.

Abstract: The invention provides for modifications to conventional optical data storage media to reduce the amount of raw material necessary in the media construction. More particularly, a portion of a thermoplastic substrate is modified to create one or more substantial void areas compared to a conventional substrate that defines flat parallel surfaces without void areas. The configuration, number, and size of the voids may be modified in order to substantially reduce inherent raw material cost while maintaining the specified physical thickness, clamping area, and mechanical stability of the medium.

Abstract: The invention is directed to self-referenced holographic recording techniques that make use of an element of a holographic medium to create a reference beam from a zero frequency Fourier component of a data encoded object beam. In other words, the self-referencing element may be formed on the holographic medium, rather then being a separate element of the holographic recording system. The element may comprise a diffusive element on the medium, designed to create a reference beam having controlled angles, phase and/or amplitude.

Abstract: The invention is directed to a spatial light modulator device that can improve holographic data recording systems, and various methods and systems incorporating the device. The spatial light modulator device includes a diffusive element to diffuse or scatter a data encoded object beam. For example, the diffusive element may comprise a two-layer diffusive laminate formed, a polymer dispersed liquid crystal material, or another diffusive material. The diffusive element can be formed over the output window, or may comprise the output window of the spatial light modulator device. In any case, the diffusive element can slightly scatter the data encoded object beam, which can significantly reduce undesirable zero-order burning effects in a holographic medium positioned in proximity to a Fourier transform plane.

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: Holographic data storage media having a sandwiched construction are described in which a holographic recording material is sandwiched between two substrates. The substrates may be formed with fluid containment features in proximity to outer edges of the respective substrates. Also, the substrates may be formed with centerpieces that are recessed relative to the outer surfaces of the respective substrates. Such substrate features can improve and simplify the media fabrication process and may improve media quality.
