Abstract

Opisan je nosilac zapisa koji ima servo stazu (4) koja ukazuje na informacionu stazu (9) namenjenu za snimanje blokova informacija. Servo staza (4) ima periodicnu promenu nekog fizickog parametra sa unapred odredjenom frekvencijom, kao i modulisane delove za kodiranje pozlcione informacije na jednakim intervalima. Modulisani delovi pocinju sa elementom sinhronizacioni bit i tipa su podataka koji ima element bit podataka ili su tipa sinhronizaciona rec koji ima element sinhronizaciona rec. Element sinhronizacioni bit, element sinhronizaciona rec i element bit podataka su modulisani prema istom unapred odredjenom tipu modulacije sa periodicnom promenom. Rastojanja izmedju svih elemenata bita koji obrazuju modulacije sa periodicnom promenom. Rastojanja izmedju svih elemenata bita koji obrazuju modulisane delove su jedinstvena. Dalje je opisan i uredjaj za citanje i/ili snimanje nosioca zapisa.
