Abstract
PURPOSE:To suppress peak shift and to prevent an error from being generated, by providing a means to identify the pattern of digital data read out from a medium and a means which applies several kinds of delay on the digital data, and selecting a delay quantity by the above identification means. CONSTITUTION:A circuit system is classified roughly to a pattern identification means 31 which identifies the pattern of the digital data 32 read out from the medium and inputted to the circuit system, and a delay quantity control means 30 which controls the delay quantity of the digital data. Furthermore, to the pattern identification means 31, a window signal 33 generated phase-locking with the input digital data 32 by a certain kind of PLL circuit so-called as a VFO circuit is also inputted. Then, the peak shift is reduced by correcting the pulse interval of the digital data by an output signal from the pattern identification means 31 by using the delay quantity control means 30. In such a way, it is possible to correct the peak shift due to waveform interference.
