A measurement method of nonlinear transition shift (NLTS) and the write precompensation in the shingled magnetic recording (SMR) are studied. In SMR R/W channel using a discrete granular medium composed of the discrete Voronoi diagram, we measure the NLTS and show had the previous track influences to the NLTS of the current track. We propose a new write precompensation by considering the recording sequence in previously recorded adjacent track, and evaluate our proposed write precompensation method by the remained NLTS and the bit error rate (BER) performance for the SMR R/W channel under a recording density of 4 Tb/in2. It is clarified that our proposed write precompensation method prevents the NLTS, however the BER performance a little degrades compared with that of the case without the write precompensation. |
