摘要： A buffer memory is used to store data from the input/output device arrayed corresponding to the data rate of said input/output data device. A threshold is selected for beginnig an unload cycle of the buffer memory which will permit said buffer memory contents to be completely transferred at the higher channel data rate to the channel during the remaining time additional data is being accumulated in the memory. The threshold selection is adaptive such that subsequent data block lengths are utilized to calculate a new threshold maintaining data transfer rates from the input/output device into the channel at an optimum value.

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.

摘要： A magnetic tape drive simultaneously senses on a magnetic tape three evenly spaced-apart servo track areas for servoing a multi-track magnetic head to follow a concurrent set of data tracks on the magnetic tape. The data tracks are arranged into a plurality of track groups. Each track group has a first and second subgroup of data tracks. The first subgroup of tracks are scanned in a first relative motion of the magnetic tape and magnetic head as a forward direction (tape is being spooled from a supply tape reel). The second subgroup of tracks are scanned in a second relative motion of the magnetic tape and magnetic head that is opposite in direction to the first relative direction and is a forward direction of scanning. While writing data in any one of the plural track groups, a servo dropout affecting most of the servo track areas is detected and indicated as a servo error. Writing is aborted. The relative position of the magnetic tape and head is detected at both longitudinal ends of the servo dropout. A servo dropout block (SDB), a tape control block, is written at each longitudinal end of the servo dropout only in the group of tracks in which data are being written. The tape space between the two SDBs is termed a limited portion of the tape in which no recording is permitted.
