Abstract: A synchronous digital demodulator and method for demodulating a read signal including a user data waveform and a servo waveform which are generated by a read head as the read head passes over a user data area and a servo area, respectively, on a medium in a storage device. The user data waveform is converted to a series of digital user data values at a user data sample rate. The series of digital user data values are then applied to a user data detector circuit. The servo waveform is converted to a series of digital servo values at a servo sample rate, which is independent from the user data sample rate. The series of digital servo values are demodulated synchronously with the servo waveform to produce a position error value indicative of a position error of the read head relative to a location on the medium.
