Abstract
Dropout produces amplitude and high frequency loss in the read signal produced by reading a magnetic tape. A system for dropout compensation includes an adaptive filter that filters the read signal using multiplicative weighting factors based on an error signal. A detector receives the adaptive filter output and produces a binary signal indicating data written onto the magnetic tape. A shaping filter receives the binary signal and produces an ideal read signal representing the read signal resulting from writing and subsequently reading the binary signal without dropout. A differencer determines the error signal by subtracting the adaptive filter output from the ideal read signal.
