ABSTRACT:
A system for the position control of a write-read head for information carriers with a magnetic storage layer, having optical servo tracks. The servo tracks consist of periodically interrupted lines, whose period length is constant and whose phase relationship differs for adjacent servo tracks. An optical scanner is connected to the magnetic write-read head and is provided with a diaphragm which transmits at the most one line section and at least one overlap between two adjacent line sections to the scanner.
