The disclosed embodiments generally relate to a data storage device for accessing a magnetic tape. The device includes write heads writing data tracks on the magnetic tape and control circuitry configured to: (1) use the heads to write a first set of data tracks on the magnetic tape; (2) measure a distortion of the first set of data tracks after the first set of data tracks have been written; and (3) use the heads to shingle write a second set of data tracks relative to the first set of data tracks based on the measured distortion. To compensate for the distortion, a priority servo is chosen based on whether the distortion is an expansion or contraction, and/or whether the shingle writing direction is inbound or outbound. The head bar is moved during shingle writing toward the servo track associated with the priority servo.
