ABSTRACT:
A recorded information reproducing apparatus which can remove a crosstalk of a read signal read from a recording medium which was high density recorded without decreasing a recording capacity of a recording medium. The apparatus obtains a first read sample value series by reading and sampling recorded information from a track on the recording medium, obtains a second read sample value series by reading and sampling recorded information from neighboring tracks adjacent to the track, and obtains a crosstalk component by filtering processing the second read sample value series in a variable coefficient filter. A result obtained by subtracting the crosstalk component from the first read sample value series is obtained as a read sample value series. A coefficient of the variable coefficient filter is updated so that a zero-cross sample value extracted from the read sample value series is converged to zero.
