Using component position error signals (PES) to measure tape distortion |
摘要 |
A method, system and program for measuring magnetic tape track distortion are provided. The invention comprises defining specifications for tape track distortion acceptability and using tape head servo readers to collect component position error signal (PES) data from servo tracks on a magnetic tape. The separate PES data are analyzed to determine tape distortion. The data can also be adjusted for reliability factors that might affect the confidence of the PES data. The distortion data for the tape is then compared to the defined specifications and a determination is made as to whether the tape meets acceptability standards.
