In one embodiment, a vibration affecting the disk drive may more significantly impact the servoing of the heads over the disk surfaces that are closest to the enclosure of the disk drive. That is, in a disk drive having multiple disks clamped to the spindle motor, the top disk surface of the top disk and the bottom disk surface of the bottom disk are typically more significantly impacted by a vibration affecting the enclosure. Accordingly in one embodiment, the first set of servo sectors 22₁-22_N may be written to the top surface of a top disk and the second, staggered set of servo sectors 24₁-24_N may be written to the bottom surface of a bottom disk. In one embodiment, the second set of servo sectors 24₁-24_N may be written at a phase offset less than 180 degrees as described above to improve the off-track detection of a vibration affecting the top surface of the top disk and the bottom surface of the bottom disk.
