    摘要: Provided are a method, storage controller, and tape drive for adjusting read heads based on misregistration calculated from servo patterns. A plurality of first read heads read a plurality of servo patterns on a storage medium. A determination is made from the read servo patterns a skew at which the first read heads are positioned with respect to the servo patterns written to the storage medium. A determination is made of an adjustment factor to eliminate the determined skew. A plurality of second read heads that read the storage medium are adjusted by the adjustment factor.

    摘要: A method for performing write calibrations on holographic storage media is disclosed. Initially, five identical and known calibration holograms are written on a holographic storage medium, in which three of the five calibration holograms are written with different laser power and three of the five calibration holograms are written with different time durations. A matched filter is then utilized to determine a cross-correlation between the five calibration holograms read from the holographic storage medium and their corresponding ideal calibration holograms previously stored within a memory device within the holographic storage drive. A least-squares fit of an ellipsoidal parabola to the cross-correlations is subsequently calculated to yield an optimal laser write power level and an optimal duration for a laser write pulse.

    摘要: Provided are a method, system, and article of manufacture for providing removable storage management services using removable storage error information. Read/write error information is obtained for at least one removable storage by interfacing with the removable storage manager. The obtained read/write error information for the at least one removable storage is processed to determine read/write error rates for the at least one removable storage. A determination is made as to whether the determined read/write error rates for the at least one removable storage exceed at least one read/write error threshold. At least one message is sent to the removable storage manager to replace the at least one removable storage having read/write error rates that exceed the at least one read/write error threshold.

    摘要: A method to store information in a holographic data storage medium, wherein the method supplies a holographic data storage medium comprising an encoded focusing hologram and one or more encoded data holograms. The method disposes the holographic data storage medium in a holographic data storage system, and disposes a rotatable imaging lens at an (i)th orientation. The method illuminates the encoded focusing hologram to generate an (i)th reconstructed focusing image, projects that (i)th reconstructed focusing image through the rotatable imaging lens, and onto at optical detector array. The method then calculates an (i)th measured focusing metric, and determines if the (i)th measured focusing metric is greater than or equal to the threshold focusing metric. If the (i)th measured focusing metric is greater than or equal to the threshold focusing metric, then the method decodes the one or more encoded data holograms.
