APPARATUS FOR DETECTING FLAW OF RECORDING MEDIUM

摘要: PURPOSE:To reduce the erroneous ratio in reading of data as whole an apparatus, by setting a flaw detection level having to judge presence or absence comparison with voltage track. CONSTITUTION:The recording content medium 10 is read magnetic head 1 while peak held hold circuit 4 through amplifier 2 and rectifier 3 output signal (c) averaged one track average 8 be inputted 9 along count 7. Further, are compared 5 equal less than set pulse number thereof stored position memory 6. At this time, counted 7 so that value brought max. flaws accommodated avoiding function utilized possible.
