    摘要: A system according to one embodiment includes a processor; logic in the processor and/or a memory configured to determine a furthest physical position on a magnetic medium that unobscured data has been written to; and logic configured to store an indicator of the furthest physical position on at least one of the magnetic medium and a memory coupled thereto. A system according to another embodiment includes a processor; logic in the processor and/or a memory configured to receive an instruction to obscure data on a magnetic medium; logic configured to read an indicator of a furthest physical position on the magnetic medium that unobscured data has been written to; and logic configured to cause obscuring of the unobscured data on the magnetic medium, and terminating the obscuring upon reaching the physical position in the indicator.

    摘要: A computer-implemented method, apparatus and computer-program product for writing data to a tape data storage medium. The method comprises providing a system service that an application invokes to handle data synchronization events associated with writing a group of files to the tape medium; keeping track of the files and data blocks in each file while writing the files to the tape medium based on file boundaries; and responsive to a data writing failure, invoking the system service to determine the files affected by the data writing failure.

    摘要: A method to write information to an information storage medium. The method creates one or more objects comprising information and provides a first one of those one or more objects. The method writes a header label to an information storage medium, where the header label comprises an object processing indicator. The method assigns a first sequence number to the first object and writes that first object to the information storage medium beginning at a first blockid and ending at a second blockid. The method writes a trailer label to the information storage medium, where that trailer label comprises an embedded object field count. The method writes an object information block to the information storage medium, where that object information block comprises the first sequence number, the first blockid, and the second blockid.
