Abstract
(EN) In an information recording, a first data processor divides input data into a plurality of frames so as to arrange the plurality of frames for each unit block. The unit block is a unit o error-correction with respect to the input data and the frames include first identification information, respectively. A second data processor inserts a linking block (LB) on a boundary portion between unit blocks in the record data. The unit blocks are adjacent to each other. The linking block (LB) includes a second identification information and the second idenditification information is different from each of the first identification information. A controller controls to record the unit block and the linking block on the information recording medium.
(FR) Dans un appareil d'enregistrement d'information, un premier processeur de données divise les données d'entrée en une pluralité de trames de manière à disposer cette pluralité de trames pour chaque bloc d'unité. Le bloc d'unité est une unité de correction d'erreur par rapport aux données d'entrée et les trames comprennent, respectivement, une première information d'identification. Un second processeur de données insère un bloc de liaison sur une partie limite entre des blocs d'unité dans les données d'enregistrement. Les blocs d'unité sont adjacents les uns aux autres. Les blocs de liaison comprennent une seconde information d'identification et cette seconde information d'identification est différente de chaque première information d'identification. Une unité de commande commande l'enregistrement du bloc d'unité et du bloc de liaison sur le support d'enregistrement d'information.
