Abstract

Une information multimot est codée en fonction de symboles multibit en relative contiguïté par rapport à un support, des fonctions d'entrelacement de mots et à code de protection contre les erreurs étant prévues simultanément. Ainsi, des indices de localisation d'erreur peuvent être produits dans des groupes à mots multiples, lesdits indices apparaissent dans des mots indices à protection élevé et sont dirigés contre des mots cibles à faible protection. De plus, les mots indices peuvent avoir une première taille homogène et peuvent être intercalés d'une première manière homogène. Les mots cibles peuvent présenter une deuxième taille homogène et être intercalés d'une deuxième manière homogène. L'organisation peut être notamment appliquée à une mémoire optique.
