Information recorder and information recording method for recording data after an occurrence of off track writing
According to one embodiment, an information recorder includes: a determination module; a storage module; a reader; and a writer. The determination module determines whether a position of a head for writing data is off a target track of a recording medium. The storage module temporarily stores therein data written by the head. The reader reads, if it is determined that the head is positioned off the target track, first data written in a sector which is considered overwritten by the head positioned off the target track among sectors of an adjacent track adjacent to the target track, from the storage module. The writer writes, if it is determined that the head is positioned off the target track, the first data into a sector positioned later than the sector into which data is written at the time the head is positioned off the target track.
