摘要：
Shingled magnetic recording (SMR) has been predicted as one of the novel technologies to extend the areal density beyond 1 Tb/in(2). It was widely thought by many researchers that very wide writers could be used for SMR, as it involves corner writing and thus writability would no longer be an issue in SMR. However, in our experimental study, we reveal that there exists an optimal write width for a given writer design due to the erase band limitations. Also we propose the optimal write width for a given shingle track pitch condition. (C) 2014 AIP Publishing LLC.
