Abstract
A disk device includes magnetic disks, ramps, suspensions, and magnetic disks. The magnetic disks are arranged above a housing bottom and configured to be rotated around a first rotation axis. The ramps are arranged above the housing bottom. The suspensions are configured to be rotated around a second rotation axis parallel to the first rotation axis, The magnetic heads are mounted on the suspensions, respectively. Each of the suspensions is configured to be rotated around the second rotation axis from a first position above or below one of the magnetic disks to a second position on one of the ramps. The plurality of ramps includes a first ramp and a second ramp that is above the first ramp. An inner end of the second ramp is closer to the first rotation axis than is an inner end of the first ramp.
