Abstract
A tape drive data storage apparatus incorporates a system for dynamically anticipating and resolving potential data error conditions. The system performs read and/or write data transfer operations on a tape medium, during which time it generates a track performance database representing a map of potential data error conditions occurring on the tape. As operations continue, determination is made from the track performance database whether one or more track fallout thresholds have been reached in one or more regions of the tape. If so, an error recovery bellcord action is performed to minimize the occurrence of data error conditions.
