Abstract: Software for reclaiming a storage medium. The software determines that a first storage medium storing data in a linear tape file system (LTFS) format meets a predetermined condition indicating that the first storage medium should be reclaimed. Responsive to reading requested data from the first storage medium, and responsive to determining that the first storage medium meets the predetermined condition, the software writes the requested data to a second storage medium in the LTFS format. Subsequent to writing the requested data to the second storage medium, the software reconciles the first storage medium to delete expired data. Subsequent to reconciling the first storage medium, the software explicitly reclaims remaining data on the first storage medium to the second storage medium in the LTFS format.

Abstract: Concurrent standard/high resolution logging of critical performance metrics and functional data for various functional areas including servo system, dataflow, channel, read/write, speed matching, and error recovery is achieved by segregating one or more rows of the tape map array for the purpose of logging only high resolution data. As performance data is logged to the standard resolution tape map by wrap and regional offset down tape, the reserved high resolution row logs data sequentially in the order it was processed on magnetic tape and not by its position on magnetic tape. The high-resolution performance data is concurrently logged with normal-resolution performance data as a supporting view with more detailed tape processing data should the normal-resolution performance data have inconclusive or insufficient content. High-resolution storage is structured for shorter regional logging or per-dataset logging of critical performance metrics and functional data, referred to herein as performance data.

The ribs have a major length and a minor width and are generally aligned to be parallel with a diagonal or normal bisector of the processing device. The underside rib generally stiffens the cover such that an upper surface of the cover is more apt to stay flat.
