Abstract
In case of deleting shingle-recorded data on a recording medium, it enables to completely delete the data with the number of writing times less than the number of writing times in data recording. To do so, a magnetic recording apparatus, which records the data on the recording medium in a first direction with a writing unit, controls movement of a relative position of the recording medium and the writing unit such that a quantity of the movement in a second direction perpendicular to the first direction in the data deletion by overwriting another data is larger than a quantity of the movement in the second direction in the data recording.
