    摘要： A system and method of operating a storage system is provided. The storage system includes a tape cartridge having a magnetic tape medium and a tape drive for reading and writing data to the magnetic tape medium of the tape cartridge. Performance data associated with specific operating loci (e.g., bands, directions, tracks, segments, etc.) of the tape drive and tape medium are collected, analyzed, and stored, allowing for analysis and detection of trends over time. In one example, tape usage events are monitored and when they cross a threshold the system may remove particular tapes in a preventative maintenance approach to reduce system outage. Performance data is collected and analyzed with a portion of the performance data being saved to emulated medium auxiliary memory (EMAM) on the magnetic tape, and a portion of the of the performance data saved in non-volatile storage in the drive.

    摘要： In scintillation cameras, spatial or linearity correction is accomplished utilizing a weighted average of correction vectors in the region of the apparent location of scintillation events. Such vectors are developed in a calibration step using a pinhole or slot apertured mask. On the fly, vectors beyond those next adjacent the apparent location are used for correction, which are constrained to exhibit continuity in both the functional value, and at a minimum the first derivative, but which may include continuity in higher order derivatives also. One such correction function, which insures continuity in both the functional value and its first derivative, is called a Hermite interpolation function.
