Abstract
A two-pole inductive magnetic head for a computer disk drive assembly. The head generates a stream of main pulses and secondary pulses in a readback waveform when reading data from a magnetic medium, each bit of read data represented by a respective main pulse. The head includes an integrating feature which reduces the amplitude and high frequency content of the secondary pulses in the readback waveform so as to ease the task of electronically isolating the main pulses for downstream processing of the read data.
