    摘要: A system, method and media drive for selectively encrypting a data packet. The system includes an encryption key for use in encrypting the data packet, a verification data element derived from the encryption key, an encryption engine for selectively encrypting the data packet using the encryption key, and a verification engine in electronic communication with the encryption engine. The verification engine is configured to receive the encryption key and the verification data element, determine when the verification data element corresponds to the encryption key as received by the verification engine, and prohibit encryption of the data packet by the encryption engine when the verification data element does not correspond to the encryption key as received by the verification engine.

    摘要: An optical disk device includes a pickup head, and a controller which controls the pickup head. The controller subtracting a second measured value determined from an amplitude value of the tracking error signal when the pickup head irradiates a second area of the optical disk with a first DVD laser beam, from a first measured value determined from the amplitude value of the tracking error signal output when the pickup irradiates a first area of the optical disk with the first DVD laser beam, to determine an evaluation value. The controller determining that the optical disk is the first DVD if the evaluation value is smaller than a reference value, and determining that the installed optical disk is a second DVD if the evaluation value is larger than the reference value, the second DVD optical disk having a smaller track width than the first DVD optical disk.

    摘要: A system for data storage includes a switch node, a meta-data server, a plurality of storage servers having at least one respective data storage device, and a scalable interconnect. The scalable interconnect couples the switch node, the meta-data server, and the storage servers. At least one of the switch node, the meta-data server and the storage servers includes a hierarchical storage manager (HSM). When information is received at the switch node, the HSM presents the information substantially simultaneously to the storage servers for storage at the respective data storage devices.

    摘要: A media drive system includes a housing and a drive unit at least partially disposed within the housing. A media handler arrangement defines a plurality of queuing positions for media objects, and a receiving area within the housing receives storage units defining at least one other queuing position. The drive system reduces latency through the use of the queuing positions to speed transfer and access to media objects.

    摘要: More than two copies of data in a storage management system may be managed by directing at least one virtual volume to a receiving management class within the storage management system. Each virtual volume is exported to a third multi-volume copy, unknown to the storage management system, based on the receiving management class. A manifest file is created listing each exported virtual volume.
