Off-Track Capability Simulation of Shingled Magnetic Recording Under Mechanical Track Misregistration

Shingled magnetic recording (SMR) is suitable for higher density recording due to its writing ability. We calculate the SMR's offset error rate with a probabilistic approach by using a linear geometric model. The results show the SMR's offset error rate as being a little better than conventional recording. We also quantify the error rate degradation of multiple adjacent track erasures in conventional recording, which is the largest merit of shingled recording.
