Abstract
According to one embodiment, a recording-current supplying section configured to supply a recording current used to excite a magnetic pole to thereby make a magnetic flux flow through the magnetic pole, supplies higher recording currents to those of a plurality of magnetic heads, located more outwardly in a direction along a same axis of rotation, as compared to ones of the plurality of magnetic heads, located closer to a middle position of an interval between the magnetic disks arranged at both ends in the direction along the same axis of rotation.
Claims6
A magnetic disk device comprising:
- a plurality of magnetic disks each including a recording layer, arranged at intervals from each other and rotating around a same axis of rotation;
- a plurality of magnetic heads each including a magnetic pole configured to generate a recording magnetic field in a direction perpendicular to the recording layer, and arranged at intervals corresponding to the recording layers;
- and
- a recording-current supplying section configured to supply a recording current used to excite the magnetic pole to thereby make a magnetic flux flow through the magnetic pole, wherein
- the recording-current supplying section supplies higher recording currents to those of the plurality of magnetic heads located more outwardly in a direction along the same axis of rotation, as compared to ones of the plurality of magnetic heads located closer to a middle position of an interval between the magnetic disks arranged at both ends in the direction along the same axis of rotation.
