Servo writing a disk of a disk drive is disclosed. A phase locked loop (PLL) is synchronized to first sectors previously written on a first track, and second sectors are written to a second track using the PLL, wherein a plurality of phase errors corresponding to the second sectors are saved. A correction value is computed corresponding to a selected one of the second sectors, wherein the correction value is computed in response to a plurality of the phase errors generated for a plurality of the second sectors leading the selected sector. The PLL is synchronized to the second sectors using the correction value, a third sector is written to a third track using the PLL, and a phase error is saved corresponding to the third sector.
