A method and apparatus for compensating for errors in servo systems. An
improved zero acceleration path (ZAP) correction technique is provided,
wherein selected tracks of a data storage device are used for ZAP
processing in order to reduce the overall time required to perform error
compensation for a storage device. For a given selected track to be
ZAPed, track profiles of adjoining tracks are used in addition to the
track profile of the selected track as part of the ZAP correction
determination for the selected track. Using adjacent track profiles as
part of the ZAP correction determination assists in mitigating AC track
squeeze issues that would otherwise occur when performing selective track
ZAPing.
