Abstract:
1. A data resilience component comprising: a storing component for storing a data file at a first sector along a spiral information track of an optical storage medium having a first half and a second half, the first half and the second half being non-overlapping; a creator component for creating a copy of the data file for storing at a second sector along the spiral information track, the first and second track sectors being non-adjacent; and a determining component for determining a number of sectors of the optical storage medium and for calculating, in dependence on the number of sectors determined, a number and location of redundant data bits required to space the copy of the data file from the data file, such that the first sector containing the data file and the second sector containing the copy are non-adjacent and radially opposed to each other on the optical storage medium in that the first sector is located on the first half of the optical storage medium and the second sector is located on the second half of the optical storage medium.
