Patent ID: 8675300

Claim:
An information recording device that records information on a magnetic disk using a magnetic head, comprising: a writing module configured to write data to a target track so that the target track partially overlaps a track adjacent to the target track of the magnetic disk, in which when off-track wherein the magnetic head deviates from the target track occurs, data to be written to a sector where the off-track has occurred are written to a substitute sector positioned after the sector where the off-track has occurred; a registering module configured to register position data of a temporary defective sector using the sector where the off-track has occurred as the temporary defective sector; a reading module configured to read data from the target track; and a cancellation processing module configured to perform inter-track interference component cancellation processing with respect to the data read by the reading module using data written to a track adjacent to the target track, in which when a sector adjacent to a processing target sector in a track width direction is a temporary defective sector registered in the registering module, inter-track interference component cancellation processing is performed using data written to a substitute sector corresponding to the registered temporary defective sector.
