Abstract:
A system and method for identifying signal degradation in a tape drive is disclosed in which a data signal read from the tape drive and the signal characteristics of the undecoded portion of the data stream are compared with a set of known values. The undecoded portion of the data may comprise the preamble portion of the signal and the comparison set of known values may be saved to local storage on the tape drive. If the comparison of the signal characteristics of the undecoded portion of the data stream and the known set of signal values indicates that data signal is degraded, a notification is generated that indicates that the signal at the tape drive is degraded.
