  • Disk drive generating fly height measurement from servo burst and adjusting by position error signal
    Patent number: 8873190
    Abstract: A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of servo tracks defined by servo sectors, wherein each servo sector comprises a plurality of servo bursts. The servo bursts in a servo sector are read to generate a read signal, and a position error signal (PES) is generated in response to the read signal, wherein the PES represents a position of the head over the disk. A fly height measurement (FHM) is generated in response to the read signal, and the FHM is adjusted based on an adjustment value generated in response to the PES.
