Abstract

Oppfinnelsen angår en informasjonsbærer som innbefatter kjørelengdebegrensende markeringer i et spor. Kjørelengdene til markeringene representerer hovedkanalbiter og variasjoner av en ytterligere parameter ved markeringene som representerer sekundærkanalbiter. Ikke alle markeringene har nevnte variasjoner, kun markeringer med i det minste en forutbestemt kjørelengde har nevnte variasjoner. Oppfinnelsen angår videre en innretning for koding, en fremgangsmåte for koding, en innretning for dekoding og en fremgangsmåte for dekoding.
