Abstract
Shingled magnetic recording (SMR) is regarded as the most influential technology for the next-generation magnetic recording systems. The SMR tracks are partly overlapped by each other, and the SMR systems can obtain higher area densities by increasing track per inch density. As a result, this brings more interference from the adjacent sidetracks, i.e., intertrack interference (ITI) while reading the home track. In this letter, we are interested in applying the filtering process to the squeezed tracks before recording to improve the quality of retrieved data. The preprocessing is to reduce the effect of unwanted signals from the sidetracks on the home track. The results show that the SMR system's performance is vastly improved even under the extremely severe effects of the ITI. © 2010-2012 IEEE.
