Abstract
A magnetic recording device write channel includes a write equalization encoder for generating a write equalization level signal and a digital to analog converter for converting the write data signal to analog signals for recording. The write equalization level signal from the write equalization encoding device controls an impedance value at an output of said digital-to-analog converter. The output of the digital-to-analog converter is connected to an input of the data transmission line which transmits the write data signal to a write head of the magnetic recording device. Variation in the output impedance of the digital-to-analog converter by comparison to the input impedance of the transmission line controls the level of the equalization transmitted to the write head of the magnetic recording device.
