  • Patent number: 8213102
    Abstract: A method for using magnetic tape having damaged areas is disclosed. The method may include writing data to streaming magnetic tape, determining if the data write was successful, and responding to an unsuccessful data write by interrupting the data writing and advancing the magnetic tape forward a predetermined distance. Additionally, the method may include attempting to write data at the next location on the magnetic tape and determining if the data write was successful. The method may further include repeating the steps of advancing the tape, attempting to write, and determining whether the data write was successful following any determination that an attempted data write was not successful. The method may include further include resuming writing data to streaming magnetic tape at a location where a data write is determined to be successful.

  • Patent number: 8001416
    Abstract: A magnetic tape cartridge, such as a Linear Tape Open cartridge, stores parameters in a non-volatile memory, such as a Media Auxiliary Memory page of a Cartridge Memory, for use in reading and writing to a magnetic tape. A backup copy of the parameters is made in the non-volatile memory for use in reading and writing to the magnetic tape in the event that the primary copy of the parameters becomes corrupt. If a tape drive fails to retrieve the primary copy of the parameters, the tape drive looks for the backup copy at a predetermined memory location, such as location 200h in the Cartridge Memory.
