RESUMO
Sliding Block algorithm was developed in a branch of mathematics known as Symbolic Dynamics and it consists of a systematic and efficient procedure to fineI codes with desirable characteristics. This work will present a complete discussion of this algorithm, without emphasis on the rigorous mathematical details that are inherent in it. The techniques that constitute this algorithm will also be emphasized (state mergillg and splitting) and its implementation through a software developed by the author. The software was adapted to generate RLL codes, which are codes with the objective to increase data storage density in magnetic and optical media. Several codes will be presented. Analysis of them, considering parameters like encoder and decoder complexity, and the number of states show that the resuIts were found near to the available bounds showing the efficiency of the software. It s important to remark that, though the software had been implemented to find RLL codes, it can be easily adapted to obtain other kinds of codes, with small changes in some routines of the sofhvare
