Zusammenfassung:	FIELD: optical information-carrying mediums. ^ SUBSTANCE: optical information-carrying medium consist of lead-in zone, lead-out zone and user data zone between lead-in and lead-out zones which carries user data. Pits are formed in lead-in zone, in user data zone and lead-out zone. Track pitch in all lead-in zone or its part differs from track pitch in all other zones of optical information-carrying medium. Because of reduced tracking errors and reduced cross-talk the playback of important information reliability is increased. ^ EFFECT: increased reliability which ensures recording and/or playback effectiveness. ^ 31 cl, 5 dwg
