    摘要: The present invention relates to digital rights management (DRM) for content that may be downloaded and bound to a storage device. The storage device may be an intelligent storage device, such as a disk drive, or network attached storage. In addition, the storage device is capable of performing cryptographic operations and providing a root of trust. In one embodiment, the DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. However, the binding key is not stored on the storage with the content. The content key is a key that has been assigned to the content, for example, by a trusted third party. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.

    摘要: Transmission efficiency and/or spatial resolution provided by resonant apertures can be enhanced by disposing a tip on part of the screen that extends laterally into the aperture. For example, a tip disposed on the ridge of a C-shaped aperture can dramatically improve performance. A spatial resolution of λ/50 has been experimentally demonstrated with this approach. The combination of high spatial resolution and high transmission efficiency provided by this approach enables many applications, such as near field optical probes for near field scanning optical microscopy (NSOM). Another application is high resolution electron sources, where an photoelectron emitter can be disposed at or near a tip+aperture structure such that the high resolution optical near-field provides a correspondingly high resolution electron source.

    摘要: A low cost and lightweight interchangeable lens system is provided. The lens system includes two aspheric elements that is usable both for page-based and bit-based data storage systems. The lens system has a large field of view up to ±50 degrees and a high numerical aperture up to 0.8. The invention reduces cost and weight of the objective lenses and is usable with the servoing technology. The invention provides a long working distance of 20% of the focal length and provides sufficient physical space to accommodate media and aberration corrections, which enable a media interchangeable and compatible system among the both optical recording formats.

    摘要: An improved surface plasmon resonance (SPR) sensor is provided based on direct measurement of the Goos-Hänchen effect. Sensor sensitivity is enhanced by selecting the thickness of the metallic layer of the SPR sensor to be close to a critical thickness dcr where the effect of the surface plasmon resonance on the Goos-Hänchen shift is most pronounced. Overall sensor sensitivity is surprisingly found to improve with this approach, even though the measurement is based on a second order effect (i.e., the Goos-Hänchen shift) instead of the first order reflectance change measured in conventional SPR sensor approaches. The invention is also applicable to sensors based on measurements of other non-specular reflection parameters, such as temporal shifts, frequency shifts, and/or angular shifts.

    摘要: An optical data storage system and method comprising a photopolymer medium having generally a polymerizable monomer, an active binder, a first, hologram recording polymerization initiator, and a second, data writing polymerization initiator. The monomer is preferably a cationic ring-opening monomer. The hologram recording polymerization initiator preferably comprises a sensitizer and photoacid generator which initiate a first polymerization in the medium which defines a format hologram. The format hologram recording is carried out via interference of a signal and reference beam, with the sensitizer being specific for the wavelength(s) of the signal and reference beams. The hologram recording polymerization is only partial and does not consume all of the monomer present in the photopolymer medium. A second stage, a data writing polymerization initiator, specific to a data writing beam, locally advances polymerization at selected data storage locations to alter the previously recorded format hologram, resulting in optical data storage as localized alterations in the format hologram.

    摘要: Digital data bits are stored at storage locations at plural depths within a holographic storage medium as selective, localized alterations in a format hologram. Micro-localized regions of a reflection format hologram extending throughout the medium are deleted by focusing a high-power laser beam at desired storage locations. The deletion regions have a lower reflectivity than the surrounding parts of the format hologram. Tunable-focus storage and retrieval heads, as well as dynamic aberration compensators, are used for multi-depth access. Storage and retrieval may each be achieved with a single head.
