Abstract:
1. A method of processing disks on spin stand comprising a spindle motor, the spindle motor comprising a rotor, the method comprising: clamping a first disk to the rotor, wherein the first disk comprises a reference servo pattern; clamping a second disk to the rotor; servoing a first head over the first disk in response to the reference servo pattern in order to position a second head over the second disk at a first radial location; writing first data to the second disk at the first radial location using the second head; removing the second disk from the rotor while the first disk remains clamped to the rotor reclamping the second disk to the rotor; servoing the first head over the first disk in response to the reference servo pattern in order to position the second head over the second disk at the first radial location; reading the first data from the second disk at the first radial location using the second head; and servoing the second head over the second disk in response to the first data.
