Disk drive that generates a position error signal and a fly height signal from a servo burst pattern

A method of generating information on a radial position and height of a transducer relative to a rotatable data storage disk, the method comprising:

• generating a read signal from a servo burst pattern in a single servo sector of the disk;
• generating a position error signal from contributions of radially adjacent servo bursts of the servo burst pattern to the read signal, wherein the position error signal is indicative of a radial location of the transducer relative to the disk;
• and
• generating a fly height signal from the contributions of circumferentially adjacent servo bursts of the servo burst pattern to the read signal, wherein the fly height signal is indicative of a height of the transducer from the disk.

A servo burst demodulator comprising:

• at least one filter that is configured to separate contributions of servo bursts in a servo burst pattern to a read signal;
• a position error signal determination unit that is configured to generate a position error signal based on the separated contributions of radially adjacent ones of the servo bursts to the read signal, wherein the position error signal is indicative of a radial location of a transducer relative to a disk in a disk drive;
• and
• a fly height determination unit that is configured to generate a fly height signal based on the separated contributions of circumferentially adjacent ones of the servo bursts to the read signal, wherein the fly height signal is indicative of a height of the transducer from the disk.
