Abstract
A disk drive includes a disk rotating unit, a traverse base holding the disk rotating unit, a damper member holding the traverse base, a main unit holding the traverse base through the damper member, a tray mounting a cartridge housing the disk, a driving unit that loads or ejects the tray and moves the disk in the cartridge relative to the disk rotating unit, and a traverse base holding member that is moved vertically by the driving unit relative to the main unit at the time of tray loading or tray ejection. The traverse base is held by the traverse base holding member through the damper member, and the resonance frequencies of the damper member in the radius direction of the disk as it is being loaded and in the direction of a rotation shaft are set higher than the maximum rotational frequency of the disk.
