Abstract

Run-Length Limited (RLL) codes are a key component in digital data recording, for computer storage and electronic entertainment applications according to K.A. Schouhamer Immink (1991). Hardware storage devices with high-density data, such as Compact Discs or DVD, use RLL codes. High coding efficiency (over 90%) is obtained for high-rate codes. The design of these codes using the classic graphic method is very complicated according to K.A. Schouhamer Immink et al. (1998). Therefore we propose an efficient method for high-rate codes design and different RLL family codes are designed based on it. Some new high-rate binary RLL codes are included as examples.

一种高速率RLL码设计的新方法

根据K.A. Schouhamer Immink(1991)的说法，运行长度限制(RLL)代码是数字数据记录的关键组成部分，用于计算机存储和电子娱乐应用。包含高密度数据的硬件存储设备，如光盘、DVD等，使用RLL码。高码率的编码效率可达90%以上。根据K.A. Schouhamer Immink et al.(1998)，使用经典图形方法设计这些码是非常复杂的。因此，我们提出了一种高效的高速率码设计方法，并在此基础上设计了不同的RLL族码。给出了一些新的高速率二进制RLL码的示例。
