Abstract
PURPOSE: To obtain a reproducing output without phase errors and perform recording and reproducing where error bits are not required, by differentiating reproducing signals to generate binary signals according to zero crossing by a two-way monostable circuit and subjecting them to a logical processing.
CONSTITUTION: Reproducing signals are applied to differential amplifier 36 and become binary differential signals C different in polarity and are applied to two-way stable circuit 16. Then, two sets of binary signals D and E according to zero crossing of differential signals are generated, and signal E becomes binary signal F shifted together with noise 66 through delay circuit 71 and is applied to latch circuit 72 together with signal D, and binary signal G which is not affected by noise 66 is generated from circuit 76 even if circuit 72 is triggerred by signal E, and this signal E is applied to exclusive OR circuit 77 together with signal D. The output of exclusive OR circuit 77 and signal F are subjected to AND processing by AND gate 74 and become a reproducing output which is not affected by noise, etc., and error bits, etc., are not required. Then, phase delay elements other than circuit 16 do not exist, and so, the phase slippage of the reproducing output is reduced.
