Abstract
A data recovery system and method is disclosed. Said data recovery system comprises a maximum-likelihood detector, a non-maximum likelihood detector, signal-length calculator, a determining unit and a selecting unit. The maximum-likelihood detector transforms a digital signal into a first binary signal. The non-maximum likelihood detector transforms the digital signal into a second binary signal. The signal-length calculator calculates a length of the first binary signal and a length of one previous to the first binary signal. The determining unit generates a selecting signal when the length of the first binary signal and the length of one previous to the first binary signal meet a criterion. The selecting unit coupled to the maximum-likelihood detector and the non-maximum likelihood detector, selectively outputs the first binary signal or the second binary signal based on the selecting signal.
