Abstract

The channel coding methods with the parameters of (4,k;2,5;r) have a large minimum separation between transitions (Tmin) and have extra codes for suppressing digital sum value (DSV) of coding digits. A stable detector is realized by applying suitable equalization for optical recording characteristics. By use of this coding method, a low error-rate detection is achieved on high density optical disks
