Information recording device.

摘要

There is disclosed an information recording device comprising a memory (101) for storing original signals for a plurality of adjacent tracks, and a computational circuit (103) for generating an inverse number component (C<-><1>) of a crosstalk component (C) which is considered to be mixed in during reproduction from the recording medium. The inverse number component (C<-><1>) is combined with stored data from the memory (101) to provide an actual recording signal (S) as a product of the inverse number component (C<-><1>) and the original signal (Q) to record the actual recording signal (S) onto the recording medium, thereby to cancel a crosstalk component produced at the time of reproducing the actual recording signal.
