Abstract

Nosilac zapisa koji sadrži servo stazu (4) koja ukazuje na informacionu stazu (9) namenjenu za snimanje blokova informacija koje predstavljaju znaci, koja servo staza (4) ima periodičnu promenu nekog fizičkog parametra sa unapred određenom frekvencijom, kao i modulisane delove za kodiranje pozicione informacije prema unapred određenom tipu modulacije, naznačen time, što nosilac zapisa sadrži upravljačku oblast u kojoj servo staza sadrži permanentne podatke koji su predstavljeni sa nekim drugim promenama pomenutog fizičkog parametra, koje druge promene su modulisane sa drugačijim tipom modulacije, pri čemu drugačiji tip modulacije obezbeđuje veću brzinu prenosa podataka od unapred određenog tipa modulacije. Prijava sadrži još 6 zavisnih zahteva.A record carrier comprising a power path (4) indicating an information path (9) intended to record blocks of information representing signs, which power path (4) has a periodic change of a physical parameter with a predetermined frequency, as well as modulated portions for position encoding information according to a predetermined modulation type, characterized in that the record carrier comprises a control area in which the servo path contains permanent data represented by some other changes of said physical parameter, which other changes are modulated by a different type of modulation, wherein a different type of modulation provides a higher data rate than a predetermined modulation type. The application contains 6 more dependent requests.
