A device for compensating the error signal produced by a high-speed disk system. The error signal is fed to a compensator and a bandpass filter respectively. The processed signals produced by the compensator and the bandpass filter are summed to output a compensated signal. The bandpass filter processes the rotating frequency portion of the error signal. The compensator includes a lead compensator and a lag compensator either serially connected or parallel connected.
