A microcontroller managed adaptive control system including a precompensator (76) and a passive equalizer, is provided to decrease the read error rate of a disk drive. An adaptively controllable programmable precompensator adjusts the timing of data bits (84) being written to disk recording surface with the timing adjustment being relative to the individual bit timing windows. A novel adaptively controllable programmable equalization circuit (78) is provided to enhance the peak amplitudes of data bits read high frequencies. A microcontroller is programmed to control the programmable precompensator and equalizer to determine the threshold for and subsequently enable the precompensation of the write data and, independently, the equalization of read data with respect to a given media surface. <IMAGE>
