A system for slimming pulses which represent the data stored in a hard disk drive assembly. The pulse slimming system comprises a delay line with the pulse applied in one polarity to a central tap. The same pulse is applied in the opposite polarity to taps along the delay line on either side of the central tap. The pulses applied to either side of the central tap are controllably attenuated by amplifiers controlled by a microprocessor. The signal which is present at the output of the delay line is the sum of the original pulse with the attenuated pulses applied to either side of the central tap of the delay line subtracted from the leading and trailing edges of the pulse applied to the central tap.
