摘要： Improved reliability for multi-layer media is providing by the present invention. A data stream U is received for recording to a multi-layer rotating storage medium, the data stream U comprising a sequence of data bits. Each data bit U(J) is encoded into X representation bits. A first representation bit B(1,J) is recorded onto a first layer of the storage media, the second representation bit B(2,J) is recorded onto a second layer of the storage media, etc. When a request to read the recorded data U from the storage media is subsequently received, a plurality of the X representation bits are read back from the storage media and are decoded into the original data bit U(J). In one embodiment, encoding may be performed with a convolution encoding algorithm and decoding with a PRML decoding algorithm. In another embodiment, Reed Solomon encoding/decoding may be employed.

摘要： A holographic information recording apparatus is disclosed. The holographic information recording apparatus comprises a laser light source, a beam splitter, and a reflective spatial light modulator. The beam splitter provides a reference beam and a carrier beam, where that reference beam is directed without reflection toward a holographic data storage medium. The carrier beam is reflected off the reflective spatial light modulator to form a data beam comprising an image of information. The reference beam interacts with the data beam to form a hologram comprising the image. That hologram is then encoded in a holographic data storage medium.

摘要： An apparatus, system, and method are disclosed for converting between serial data and encoded holographic data. The apparatus for converting between serial data and encoded holographic data is provided with a logic unit containing a plurality of modules configured to functionally execute the necessary steps of reading data signals from and writing data signals to a data bus on a computing device, converting between a serial data stream and an encoded data image, and reading data from and writing data to a holographic storage medium. From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method for converting between serial data and encoded holographic data. Beneficially, such an apparatus, system, and method would encode backup information directly with the data as it is written to the storage medium.

摘要： A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

摘要： An apparatus, system, and method are disclosed for aberration compensation. In one embodiment, a first compensation lens used in conjunction with a second compensation lens to produce a conical beam used to read from, or write to, an optical medium. An Nth order compensation equation is used to optimize aberration errors associated with accessing the optical medium. The present invention may include a displaceable focus lens positioned relative to an optical medium. The focus lens may be displaced when the conical beam's focal length is adjusted. A displacement equation is presented to determine the preferred placement of the focus lens. By compensating for aberration, read/write errors may be reduced while accessing optical media thus increasing system robustness and facilitating the use of additional layers on optical media.
