  • Publication number: 20120096231
    Abstract: A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

  • Publication number: 20120090763
    Abstract: A first holding table suction-holds an annular projection of a wafer remaining on a rear face thereof for surrounding a back grinding region. A second holding table having an outer peripheral wall adjacent to an inner wall of the annular projection is inserted into a flat portion inside the annular projection for joining a separating adhesive tape to a protective tape on a surface of the wafer while a flat plane of the flat portion is suction-held. Thereafter, the adhesive tape is separated. Accordingly, the adhesive tape is separated from the surface of the wafer together with the protective tape.

  • Patent number: 8161262
    Abstract: A storage system allocates a data storage area in response to an access request from a first computer if the capacity of a first physical storage device configuring a first logical storage area, provided to the first computer, is equal to or lower than a predetermined threshold. The storage system associates the first logical storage area with another physical storage device, which is different from the first physical storage device associated with a second logical storage area provided to the first computer and a second computer, and allocates a data storage area from the another physical storage device if the capacity of the first physical storage device associated with the first logical storage area exceeds the predetermined threshold.

  • Publication number: 20120085478
    Abstract: A piece of a double-faced adhesive tape cut into a substrate shape is separated from a carrier tape with an edge knife. The separated piece of the double-faced adhesive tape is joined to a substrate relatively moving at a speed synchronized to a separation speed. It is monitored whether or not the piece of the double-faced adhesive tape is in good joining condition to the substrate to which a joining process has been performed. When poor joining is detected, the piece of the double-faced adhesive tape is separated and removed from the substrate in poor joining condition, and a piece of the double-faced adhesive tape is again joined to the substrate from which the piece of the double-faced adhesive tape is already separated and removed.

  • Publication number: 20120087040
    Abstract: The present invention provides a magnetic disk inspection method and its system suitable to supply magnetic disks stored in a cassette to a plurality of inspection devices and collects inspected magnetic disks from the inspection devices. The cassette in which uninspected magnetic disks are stored is taken out from a cassette housing unit and transferred to any one of a plurality of optical inspection units. The optical disk inspection unit to which the cassette with the uninspected magnetic disks stored therein is transferred, takes out an uninspected magnetic disk and inspects both surfaces thereof. The magnetic disk whose both surfaces are inspected and which is determined as a non-defective product is stored in a cassette for collecting non-defective magnetic disks. The cassette is transferred from the optical inspection unit to the cassette housing unit. The transferred cassette is housed in the cassette housing unit.
