The invention relates to an optical disc (10) comprising a hybrid information layer with at least two congruently adjoining spirals, whereby a first spiral (12) of said adjoining spirals comprises a ROM section containing read only data and a second spiral (14) of said adjoining spirals comprises a recordable section having a pre- groove provided for tracking purposes during recording. Said ROM section and said recordable section are arranged at least partially adjoining each other thereby forming an overlap region where a track of said first spiral containing read only data is arranged next to an associated track of said second spiral containing a pre-groove. ® KIPO & WIPO 2007
