| 1. A motor for disk driving apparatus comprising:
a rotator rotating about a rotation axis, the rotator being at least partially made of a magnetic metal material;
a fixing part rotatably supporting the rotator; and
a magnetic preload magnet disposed close to the rotator to an extent that a necessary magnetic attraction force can be generated
and attached to the fixing part,
wherein the disk driving apparatus includes a disk tray capable of moving in two ways along one direction perpendicular to
the rotation axis, wherein the disk tray can be drawn to the outside of the disk driving apparatus, and
wherein the magnetic attraction force in the rotation axis direction acting between the magnetic preload magnet and the rotator
tilts the rotator along the one direction with respect to the rotation axis.
