Abstract
Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position a selected head among one or more heads proximate to a corresponding disk surface of the one or more disks; and one or more processing devices. The one or more processing devices are configured to detect adjacent track interference (ATI) due to a write operation in an adjacent sector to a subject sector on the corresponding disk surface; and to generate a readback servo trajectory for the subject sector, based on a position error signal (PES) for the subject sector, a PES for the adjacent sector, and the ATI.
