| Abstract(in English) | From some computer experiments on a TDMR simulation model, it is observed that there is strong correlation between the polarity difference of a bit and bit error rate. The polarity difference of a bit is the number of adjacent bits having opposite polarity. This correlation is due to random nature of the shape of a grain. In this report, we propose a new class of two-dimensional constraint codes which is called an adjacent polarity constrained code. This code forces the total polarity difference of a two-dimensional array to be under a certain upper limit. A simple encoding method is presented and analyzed. Finally, the bit error rate for a Voronoi discrete grain model with the adjacent polarity constrained code is evaluated with computer simulations. |
