摘要： Method and apparatus are provided for presenting various levels of detail about successful error recoveries and background hardware optimizations during the recording and retrieval of digital information on magnetic tape. A first, Band Summary, report presents a high-level summary of recovery methods by data band and wrap. A second, Detail Summary, report presents a mid-level summary of recovery methods by track and longitudinal position (LPOS) region within one wrap of a band on the tape. A third, ERP Summary, report presents a low-level summary of errors and specific recovery methods and optimizations by LPOS region within each wrap. Such “telescoping” views permit pattern analysis to be performed at different resolutions. Thus, correlations of possible interactions between hardware and microcode activities that result in changes of the nominal operating point of the drive may be identified. Possible failure patterns may also be identified and fed back to design personnel and incorporated in microcode design changes for more effective ERP.

摘要： 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.

摘要： A tape drive data storage apparatus incorporates an error recovery system that is dynamically controlled to perform knowledge-based error recovery in accordance with a novel error recovery method. As the tape drive apparatus performs read and/or write data transfer operations on a tape medium loaded in the tape drive, an error recovery knowledge base is generated representing a tape map of ECC error correction locations on the tape medium. If error recovery is initiated and it is determined from the tape map that one or more error clustering thresholds have been reached in one or more selected regions of the tape medium, appropriate error recovery action is taken depending on whether a data read or data write operation is underway. If read (or write) data is being processed, the error recovery procedures performed by the error recovery system can be selectively modified in the affected tape medium regions to address the expected cause(s) of the data error. If write data is being processed, the affected tape regions can be demarked so that data is not written thereon during subsequent write operations. In this way, error recovery and data transfer operations can be tailored based on knowledge that localized media defects have been found.
