A method for managing DI(Disc Information) of a high-density optical disc is provided to record wobbled pit-type DI in a certain recording section of a PIC(Permanent Information and Control data) zone, and to record straight pit-type DI in the reset PIC zones, respectively, thereby quickly detecting the wobbled pit-type DI by a push-pull signal method. An optical disc device consisting of an optical pickup(30), a VDP(Video Disc Play) system(31), and a D/A converter(32) firstly detects disc type information additionally recorded in a BCA area, decides a type of an optical disc, and exactly performs an initial servo operation relative to the decided type. The optical disc device quickly detects disc information recorded at a front recording section of a PIC zone in pit type by using a push-pull signal method. In a reserved area of DI, disc information size information is recorded, or flag information for showing final disc information is included.
