Data storage device with adjacent track interference-aware servo trajectories

A method comprising:

• detecting, with one or more processors, adjacent track interference (ATI) due to a write operation in an adjacent sector to a sector subjected to a write or read operation on a disk surface of a data storage device;
• and
• generating, with one or more processors, a readback servo trajectory for operating a head proximate to the sector subjected to the write or read operation, based on a position error signal (PES) for the sector subjected to the write or read operation, a PES for the adjacent sector, and the ATI.

One or more processing devices comprising:

• means for detecting adjacent track interference (ATI) due to a write operation in an adjacent sector to a sector subjected to a write or read operation on a disk surface of a data storage device;
• and
• means for generating a readback servo trajectory for operating a head proximate to the sector subjected to the write or read operation, based on a position error signal (PES) for the sector subjected to the write or read operation, a PES for the adjacent sector, and the ATI.
