Abstract
A data resilience component ensures data integrity by storing a data file and a copy thereof in non-overlapping sectors along the spiral information track of an optical storage medium. The number and location of sectors of the optical storage medium are determined, and, in dependence on this data, the number and location of redundant data bits required to space the stored copy from the stored data file, such that the first sector containing the stored data file and the second sector containing the stored copy are non-adjacent, is determined. The data file, its copy and the redundant bits are then sent in a data stream in their appropriate location to prevent the files from being adjacent for recording.
