Title (EN) OPTICAL DISK AND OPTICAL DISK DRIVE DEVICE
(FR) DISQUE OPTIQUE ET UNITE DE DISQUE OPTIQUE
Abstract: front page image
(EN)An optical disk having a plurality of substantially concentric tracks, each of which includes a plurality of segments each comprising a servo area ARs provided with servo pits for giving servo information to a disk drive and a data area ARd. Identification marks SGM, ADM, STM1, STM2 are recorded in the servo area ARs. The identification marks SGM, ADM, STM1, STM2 provide information for identifying the respective segments depending on the recording position in the servo area ARs.
(FR)Disque optique comportant une série de pistes concentriques, dont chacune comporte une série de segments comprenant eux-mêmes des zones d'asservissement ARs pourvues de creux d'asservissement conçus pour donner des informations d'asservissement à une unité de disque et une zone de données ARd. Des marques d'identification SGM, ADM, STM1, STM2 sont enregistrées dans les zones d'asservissement ARs. Ces marques d'identification SGM, ADM, STM1, STM2 fournissent des informations permettant d'identifier les segments respectifs en fonction de la position d'enregistrement dans les zones d'asservissement ARs.
