Abstract:
A crosstalk eliminating method in a recorded information reproducing apparatus having a pickup to obtain a read signal by photoelectrically converting reflection light when a reading beam is irradiated onto recording tracks formed on a recording disk, comprising the steps of:employing a reading position of said pickup for the center recording track among three adjacent recording tracks as a reference;obtaining crosstalk components based on a read signal read out from each of positions which are shifted by a predetermined distance frontward and rearward in the reading direction from said reading position on each of the recording tracks which are neighboring said center recording track on both sides thereof and a read signal read out from each position near said reading position on each of the recording tracks which are neighboring on both sides of said center recording track; andsubtracting said crosstalk components from the read signal read out from said reading position on said center recording track, thereby eliminating the crosstalks from the adjacent tracks.
