Abstract
A találmány tárgya általánosságban eljárás információnak egy korongalakú adathordozón (1) való rögzítésére, ahol az adathordozó (1) több,alapvetően koncentrikus kör alakú sávval rendelkezik. Az ilyen rögzítősávok (2) kialakíthatók különálló kör alakú sávokként vagy egyfolytonos spirális sávként. Az egyes sávok logikai blokkokra vannakfelosztva, és az adatrögzítéshez az egyes blokkok egy adat területtelrendelkeznek. Ezen felül, az egyes blokkok rendelkeznek egyterülettel, amely egy ellenőrző szám vagy ellenőrző összeg rögzítésérevan fenntartva. A találmány tárgya továbbá felvevő berendezés (20)információnak, különösen valós idejű video- vagy hanginformációnak egyadathordozón (1), különösen egy optikai lemezen való rögzítéséhez, azadathordozó több koncentrikus, alapvetően kör alakú sávvalrendelkezik. A berendezés tartalmaz: egy vezérlő egységet (22); egyíró/olvasó egységet, amely alkalmas arra, hogy egy lézersugarat avezérlő egység (22) irányításával egy adathordozó (1) egy rögzítősávjára (2) irányítson, és vegye az adathordozóról (1) visszavertlézersugarat. Továbbá alkalmas arra, hogy egy, a visszavert lézersugáralapján meghatározott nyomkövetési jelet továbbítson a vezérlőegységnek (22). Jellemzően a vezérlő egység (22) alkalmas a találmányszerinti eljárások foganatosítására. Ó
