A data storage device is disclosed comprising a head actuated over a disk comprising servo data for defining a plurality of data tracks. A plurality of zones are defined for the disk, wherein each zone comprises a plurality of the data tracks. Position error signal (PES) repeatable runout (RRO) values are generated based on the servo data in a first zone, and data sector squeeze RRO values are generated based on data segments in the first zone. A first data track format for the first zone is generated based on the PES RRO values, and a second data track format is generated for the first zone based on the data sector squeeze RRO values. 公开一种数据存储装置，其包括在磁盘上方致动的磁头，所述磁盘包括用于限定多个数据磁道的伺服数据。限定所述磁盘的多个区，其中每一区包括多个所述数据磁道。基于第一区中的所述伺服数据生成位置误差信号(PES)可重复偏转(RRO)值，且基于所述第一区中的数据段生成数据扇区压缩RRO值。基于所述PES RRO值生成用于所述第一区的第一数据磁道格式，且基于所述数据扇区压缩RRO值生成用于所述第一区的第二数据磁道格式。
