ABSTRACT:
A disc drive storage system having a plurality of data tracks and data sectors within each track, wherein each track further comprises a redundancy sector for reconstructing a data sector unrecoverable at the sector level. The latency of the storage system is minimized by generating track level redundancy data over the write range of data sectors and storing the "write" redundancy to the redundancy sector. Then during idle time of the storage system, the track level redundancy is regenerated for the entire track. If an unrecoverable data sector is encountered during the idle time redundancy regeneration, and the unrecoverable data sector is within the write range of the previous write operation, then it is reconstructed using the track level redundancy data stored in the redundancy sector.
