发明名称 RECORD CARRIER ON WHICH INFORMATION IS RECORDED IN AN OPTICAL STRUCTURE
摘要 <p>A record carrier is described on which information is recorded in an optical structure of trackwise arranged areas and intermediate areas. By adapting the average dimensions of the areas to the average spatial frequencies on the record carrier a read signal can be obtained of sufficient modulation depth and minimal distortion.</p>
