A sampled amplitude read channel reads data from a magnetic medium by detecting digital data from a sequence of discrete time sample values generated by sampling pulses in an analog read signal from a read head positioned over the magnetic medium. The digital data comprises a preamble field...http://www.google.fr/patents/US5793548?utm_source=gb-gplus-shareBrevet US5793548 - Fault tolerant sync mark detector for comparing a sign and magnitude of a detected sequence to a target sync mark in sampled amplitude magnetic recording
