Abstract:
A magnetically recorded-signal reproducer comprising:a read head using a MR element for reading code signals recorded on a recording medium,amplification means for amplifying reproduced signals output from said read head,means for sampling the signal output from said amplification means at a predetermined cycle,means for equalizing the signal output from said sampling means in accordance with a predetermined equalization rule, andmeans for judging the recorded codes read by said read head, wherein;said means for equalizing comprising:a plurality of multistage-connected delay elements for delaying signals output from said sampling means,a plurality of coefficient processing units each being inputted the signal from the input tap and the output tap of one of said delay elements or the input tap of a first-stage delay element and the output tap of the first-stage delay element to provide a signal output,an adder for adding the signal outputs from coefficient processing units.
