摘要

参数为(4,k;2,5;r)的信道编码方法具有较大的最小过渡间隔(Tmin)，并且具有用于抑制编码数字的数字和值(DSV)的额外代码。通过对光记录特性进行适当的均衡，实现了稳定的检测器。利用这种编码方法，可以在高密度光盘上实现低错误率的检测。

Variable length RLL codes for high-density optical recording

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.<>
