ABSTRACT:
There is disclosed an information recording device composed of a memory for storing an original signal from a plurality of adjacent tracks, and a computational circuit for generating an inverse number component of a crosstalk component which is considered to be mixed in during a reproduction process on the basis of storage data from the memory to provide an actual recording signal as a product of the inverse number component and the original signal to record the actual recording signal onto the recording medium, thereby canceling a crosstalk component produced at the time of reading by the inverse number component of the crosstalk component included in the actual recording signal when the actual recording signal has been read.
