Abstract
A method and apparatus for protecting a disk from overwrites during mechanical shock. If the PES exceeds an off-track threshold for a predetermined number of servo samples, the read/write is suspended for a predetermined duration. The predetermined duration allows for the mechanical shock or disturbance to abate and allows the heads to settle with respect to the track. The off-track threshold being exceeded for several servo samples is used as an indicator of the mechanical force and subsequent undesirable vibration. The writes can then be suspended for the predetermined duration, thereby avoiding overwriting data on adjacent tracks.
