Title (EN) METHOD OF RECORDING DATA ON AN OPTICAL DISC
(FR) PROCEDE D"ENREGISTREMENT DE DONNEES SUR UN DISQUE OPTIQUE
Abstract: front page image
(EN)A method of recording data on an optical disc (10) having already recorded thereon one or more bands or segments of data each comprising a plurality of tracks and having a portion for producing an end-of-band signal indicative of the last recorded track the respective band. After sensing the end-of-band signal of the last recorded band, a relative radial movement is brought about between a recording means and the disc (10) by a distance corresponding to a predetermined number of tracks to produce a gap (18) between the last recorded band and the next band to be recorded and recording of the next band is then commenced. The distance is determined experimentally with a view to compensating for the eccentricity errors likely to be encountered in practice when recording on an optical disc (10) at a predetermined density.
(FR)Procede d"enregistrement de donnees sur un disque optique (10) possedant deja un enregistrement sur une ou plusieurs bandes ou des segments de donnees chacun comprenant une pluralite de pistes et ayant une partie pour produire un signal "fin-de-bande" indicatif de la derniere piste enregistree de la bande respective. Apres detection du signal "fin-de-bande" de la derniere bande enregistree, est engendre un mouvement radial relatif entre un moyen d"enregistrement et le disque (10) d"une distance correspondant a un nombre predeterminee de pistes pour produire un intervalle entre la derniere bande enregistree et l"enregistrement de la prochaine bande est alors commence. La distance est determinee experimentalement en vue de compenser les erreurs d"excentricite qui peuvent se rencontrer dans la pratique lorsqu"on enregistre sur un disque optique (10) avec une densite predeterminee.
