MAGNETIC RECORDING APPARATUS AND CONTROLLING METHOD OF MAGNETIC RECORDING APPARATUS

摘要

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.

主权项

1: A magnetic recording apparatus comprising:
a writing unit configured to form a recording column extending in a first direction, by applying a recording magnetic field to a recording medium; a moving unit configured to move a relative position of the recording medium and the writing unit to a second direction perpendicular to the first direction; and a controlling unit configured to control the writing unit and the moving unit such that, on the recording medium, the recording columns mutually adjacent in regard to the second direction partially overlap in the second direction, wherein the controlling unit controls the moving unit such that a quantity of movement in the second direction in a case of deleting information written on the recording medium by overwriting with the writing unit another information on the recording column in which the information has been written is larger than a quantity of movement in the second direction in a case of writing information on the recording medium with the writing unit, and wherein the writing unit, the moving unit, and the controlling unit are implemented by at least one circuit.
