Abstract

Pronalazak se odnosi na nosilac informacija koji sadrži znakove, koji su kodirani sa kompresijom, na stazi. RLL Dužine kodova znakova predstavljaju bitove glavnog kanala i varijacije narednog parametra znakova predstavljaju bitove sekundarnog kanala. Svi znaci nemaju pomenute varijacije, već samo znaci sa najmanje unapred odredjenom dužinom koda imaju pomenute varijacije. Pronalazak se dalje odnosi na uredjaj za kodiranje, na postupak za kodiranje, na uredjaj za dekodiranje i na postupak za dekodiranje.[The invention relates to an information carrier comprising runlength limited marks in a track. The runlengths of the marks represent main channel bits and variations of a further parameter ofthe marks representing secondary channel bits. Not all marks have said variations, only marks of at least a predetermined runlength have said variations. The invention further relates to a device for encoding, a method for encoding, a device for encoding and a method for dcoding.
