Abstract
A disk drive device includes: a rotary arm rotatable according to loading of a disk between a draw-in position and an eject position for ejecting the disk from a housing; a drive mechanism providing driving force for the rotary arm; a link arm mechanism interconnecting the rotary arm and the drive mechanism and rotating the rotary arm from an insertion position to the eject position when ejecting the disk; and a guide cam having a guide edge on which a guide projection of the link arm mechanism slides when ejecting the disk to rotate the rotary arm in an ejecting direction via the link arm mechanism, the guide projection moving around the guide cam from insertion to ejection of the disk. Engagement between the guide projection and the guide edge is released when a force opposite to a rotation direction is applied to the rotary arm when ejecting the disk.
