Abstract: PURPOSE:To effectively perform error checking and simultaneously to perform a necessary measure by detecting abnormality. CONSTITUTION:A read signal is amplified by an AGC amplifier 82, the wave height value of a burst-signal provided on the frontest position of respective sectors is compared with a standard voltage VS by a comparator 85.
