Abstract
According to one embodiment, an information reproducing apparatus is configured to obtain, from a read sample value sequence obtained by sampling a read signal read from a first recording track of a magnetic recording medium, an interference-component-removed read sample value sequence, from which an interference component from a second recording track adjacent to the first recording track is removed. The apparatus includes a decoding module. The decoding module is configured to generate a first interference-component-removed read sample value sequence based on a cancellation weight column which varies according to a difference in polarity between a first bit of the first recording track and a second bit of the second recording track adjacent to the first bit.
