METHOD AND DEVICE FOR REPRODUCING DIGITAL SIGNAL

PURPOSE:To realize a recording/reproducing device with the high reliability for a recording code with a minimum run length 3. CONSTITUTION:A signal regenerated from a recording medium 4 is dealt with in two bits, and is equalized by a reproducing equalizer circuit 6 so as to become an output when 11>an reference output>the output when 00 making the output when a recording signal is 10 or 01 the reference output. Then, the output is identified to a ternary by a clamping circuit 7 and an identification operation circuit 8, and the low frequency component of a regenerative signal is compensated by operating an original recording code by the identification result and a record encoding rule. Thus, an identification interval is made two bits, and the device capable of dealing with the high speed recording data is provided.
