Abstract:
A read channel in that reads data from a magnetic storage media. An analog signal produced by passing a read head over magnetic storage media is amplified to match the range of an analog to digital converter (ADC) range. A baseline adjustment is performed on the amplified analog signal to center the amplified analog signal to a midscale of the ADC, which may be based on an error feedback signal and/or a decision feedback signal. Read channel compensation may then be performed after the baseline adjustment has been applied. The read channel compensated analog signal is sampled with the ADC to produce a digital signal. This digital signal may be filtered and a bit sequence may then be detected from the filtered digital signal. The EFB signal and/or the DFB signal may be produced in the digital domain based on the digital signal and the detected bit sequences.
