IPC: G11B20/02
Filed: 1987-08-14
Abstract: PURPOSE:To effectively reduce noise by registering an expected noise waveform to a memory, obtaining the correlation between the waveform and a reproducing signal, subtracting the noise waveform when the correlation exists, and supplying the waveform and the signal to the signal reproducing system at rear stage as they are. CONSTITUTION:The noise waveform, which has a risk to be superimposed on the reproducing signal due to a flaw occurring in a recording medium, is registered beforehand to a noise waveform memory 12 composed of a ROM, etc., as a digital signal form. The correlation between a reproducing waveform and the noise waveform is calculated by reading the noise waveform and the reproducing signal respectively from the noise waveform memory 12 and a work RAM 13, repeating a processing to add the product of the both while gradually staggering the reading timing of one of them. When it is decided that the correlation exists, the reproducing signal and the noise waveform are read out again from the work RAM 13 and the noise waveform memory 12, the difference between both are prepared, and the difference is written into an output buffer 17. Thus, the noise can be effectively reduced.
