摘要
指出了游程长度受限码(RLL码)的性能评定的指标与结构参数间的关系,以及结构参数相互间的联系;提出了以提高线性记录密度为目的的优化选择结构参数的准则,同时对常用的几种RLL编码方式进行了比较。
The relation between parameters of the RLL code and its performance criteria, and the relation among RLL code parameters is analysed in detail. The principle of optimal selection of RLL code parameters which achieve high linear density is also proposed. Comparisons of several RLL codes are given at last.
