<p>6085/175 A method is disclosed for verifying the integrity of servo data stored as a series of parallel servo tracks on a disk. Each track includes automatic gain control data and servo positioning data. The peak amplitudes of the automatic gain control pulses on a first track determine a first threshold level. The first threshold level is then shifted to a higher, enhanced threshold level. Servo data pulses from a second track are then detected, based on the enhanced threshold level. Should these servo data pulses not be fully detected, an error is recorded for the second servo track. MPI 770-CA</p> |
