  • Patent number: 7826169
    Abstract: A method for detecting errors in a servo system of a magnetic storage drive includes writing a plurality of data tracks at a pitch, detecting a position of an edge of at least two of the data tracks under control of a servo system (e.g., an optical or magnetic servo system), and determining an error in the servo system based on the detected positions and known pitch of the data tracks. Differences in the track edge positions of the tracks from the positions at which they were written may indicate errors in the optical servo system (e.g., non-linearity errors, as well as other errors such as electrical, temperature, or the like). Determined errors may be stored with a look-up table of positional errors or used to normalize a position algorithm associated with the servo system.

  • Patent number: 7177108
    Abstract: A system and method of operating a storage system is provided. The storage system includes a tape drive for reading and writing data to a magnetic tape medium of a tape storage media device, and an auxiliary memory emulator for receiving I/O commands to perform I/O operations on an auxiliary memory and for rerouting the commands to perform the I/O operations on the magnetic tape medium of the tape storage media device. The method includes receiving I/O commands to perform I/O operations on an auxiliary memory on a tape storage media device, wherein the tape storage media device includes a magnetic tape medium and does not include the auxiliary memory, and routing the I/O commands to the magnetic tape medium provided in the tape storage media device.
