Abstract
In a disc reproduction apparatus 1 for reproducing information signals from a disc recording medium whereon a first synchronization pattern is formed on a recording track in predetermined cycles and more than one second synchronization pattern with fewer bits than the first synchronization pattern which has been recorded between first synchronization patterns adjacent to each other, second synchronization patterns are detected without fail and highly accurately. The timing of a second synchronization pattern detecting means 7 for fetching the reproduction signal R is made variable through making the window width of window signal WIN variable based on the results (F1 and F2) of the detection of first and second synchronization patterns by first and second synchronization pattern detecting means 6 and 7.
