    摘要: A Blu-ray Disc™ optical disk for video and/or audio applications comprises a data layer having in-pits recessed into a surface of at least one data layer and on-pits elevated above the surface of at least one data layer, and further having a substrate layer disposed on each data layer. The in-pits and the on-pits may be disposed in the same data layer or on different data layers. The in-pits and the on-pits are indistinguishable from each other when read using an optical drive, and the in-pits and the on-pits are observable by SEM cross-section of the data layer of the Blu-ray Disc™ optical disk. A method for anti-piracy tagging a Blu-ray Disc™ optical disk by patterning a data layer to have in-pits and on-pits is also provided, wherein the in-pits and the on-pits are indistinguishable from each other when read using an optical drive, and are observable by SEM.

    摘要: An approach to power economization in a spoke and hub environment is presented. When a hub receives a data set from a first spoke, the hub writes the data set to a first partition that is associated with the first spoke. After the data transfer is complete, the hub powers down the first partition. If the first spoke sends additional data transfers to the hub while the first partition is powered down, the hub stores the additional data transfers in a second partition. When the first partition is powered up again, the hub moves the data intended for the first partition and that was stored in the second partition. The data is moved from the second partition to the first partition. The hub may monitor the size of the addition data transfers. If the data transfer is large, the hub may power up the first partition, write the data in the first partition, and move to the first partition any data that was intended for the first partition but written to the second partition while the first partition was powered down.

    摘要: A servo track has identical servo pattern frames including two pairs of parallel magnetic transitions, the transitions of each pair spaced apart an equal distance, the transitions of the first pair at an azimuth angle to the longitudinal axis of the tape, the transitions of the second pair at an opposite azimuth angle. A servo channel receives signals at first times corresponding to when a servo read head detects the first and second transitions of the first pair of parallel transitions of a servo pattern frame, and second times corresponding to when the servo read head detects the first and second transitions of the second pair of parallel transitions. The servo channel determines a relative lateral movement and velocity between the tape and the tape head based on the azimuth angle and the ratio of the difference of the first and the difference of the second times.

    摘要: Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with a second CRC seed. Subsequent to reading the deduplicated data, the first CRC seed is associated with the undeduplicated data, and the second CRC seed is associated with the stub. A CRC check is performed using one of the first and second CRC seeds. If the CRC check is positive, an I/O operation is allowed to proceed. If the CRC check is negative, an additional CRC check is performed using another one of the first and second CRC seeds.
