Device and method of reading and writing data on magnetic recording medium in case of off-track occuring
According to one embodiment, there is provided an information recording device that records information on a magnetic disk using a magnetic head. The registering module registers position data of a temporary defective sector using a sector where an off-track has occurred as a temporary defective sector. The reading module reads data from a target track. The cancellation processing module performs 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.
