Abstract
Multiword information is encoded as based on multibit symbols in relative contiguity with respect to a medium, whilst providing wordwise interleaving and wordwise error protection code facilities. This may provide error locative clues across words of multiword groups, that originate in high protectivity clue words and point to low protectivity target words. The clue words may have a first uniform size and be interspersed in a first uniform manner. The target words may have a second uniform size and be interspersed in a second uniform manner. The organization may be applied for use with optical storage. Sectors may get provisional protectivity as a low-latency error correction mechanism.
