Abstract: PROBLEM TO BE SOLVED: To provide a disk drive which can reduce the flow velocity of an airstream generated near a magnetic disk during the rotation of the magnetic disk in a HDD having a high rotational speed, that is, can restrict the occurrence of a flutter. SOLUTION: The interval between magnetic disks 22b and 22c located in the center in the axial direction among a plurality of magnetic disks 22a, 22b, 22c, and 22d is set more largely than the interval between other magnetic disks 22a and 22b and the interval between 22c and 22d.
