The data recording apparatus for recording data to a recording medium having one or more tracks arranged in parallel comprises a data recorder configured to record data to the one or more tracks, a memory configured to store data, and a controller configured to control the data recorder. The controller determines whether or not the one or more tracks include a data defective region in which the data has not been recorded properly, stores in the memory the data that has not been recorded properly, designates a position corresponding to the data defective region, which is in a track arranged in parallel to the data defective region, and reads from the memory the data that has not been recorded properly, and records that data to the position corresponding to the data defective region.
