Abstract
A disk mounting device, in a disk drive unit for rotating a disk-shaped recording medium while writing information on and/or reading information from it, includes an attracting magnet to magnetically hold the recording medium. The attracting magnet is mounted directly on the rotor yoke of a disk drive motor. With this arrangement, the height of the disk mounting device, as well as the height of the disk drive unit incorporating the disk mounting device, can be reduced.
