    摘要: Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.

    摘要: The present techniques provide methods and systems for reading and processing a data signal read from an optical data disc. In embodiments, an optical reader system may read data bits from a data ring in the disc. The data rings may be concentric, and a beginning of a sequence of data on the data ring may be in substantially the same position as an ending of the sequence. The reader may identify a data ring and begin the read process on the targeted data ring, and may end the read process when the reader reaches the starting point. The data sequence read from the data ring may be decoded to form a bit stream, which may be provided to various output devices. A circular trellis formed from the bit stream may enable the reading of a targeted data sequence without additional tail bits to improve data transmission efficiency.

    摘要: Provided are methods and systems of managing a handoff in a multimedia communication network. Embodiments include estimating the voice quality of a communication route in the network. The voice quality may be estimated by using a total voice quality metric involving subtracting various impairments to the voice signal. Impairments may result from the type of vocoder in a communication route, the error or loss associated with RF links and network links, and delays in the communication route. After subtracting the impairments to obtain the total voice quality metric for the communication route, the total voice quality metric may be compared with a threshold and/or other total voice quality metrics of other communication routes to determine whether and when a handoff should be made.

    摘要: The present techniques provide methods and systems for more reliable reading of optical data disks. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The pattern may include light scattered from a single bit that may be under a center detector, as well as light scattered from proximate bits. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the presence or absence of a bit or bits of data. The mathematical combination may also use data that is known about the status of adjacent data bits (such as previously read bits, or bit patterns which are allowed or not allowed by specific data encoding schemes) to improve the accuracy of the bit prediction.

    摘要: Techniques are provided for controlling the reading of micro-holograms from a holographic disk based on a target data layer to be read in the disk. Reading a target data layer which is relatively deeper in the disk (e.g., farther from an optical head emitting a reading beam) may involve using a higher power reading beam to compensate for power attenuation of the returned reading beam. For example, a power adjustment module may be used to dynamically adjust a reading laser emitting the reading beam, based on the dynamically changing target data layer. By compensating for power attenuation in deeper target data layers, the variance of power in the returned reading beams may be decreased, possibly improving the bit error rate in micro-hologram reading techniques.
