Abstract:
1. A disk drive device comprising: a housing having a slot through which a disk-shaped recording medium having a recording surface is inserted and ejected; a mount that is disposed in the housing and on which the recording medium inserted through the slot is mounted; a conveying mechanism including an arm unit that extends and retracts along a plane substantially parallel to the recording surface of the recording medium to convey the recording medium between the slot and the mount while holding a peripheral portion of the recording medium; and a restricting unit that restricts the movement of the arm unit; wherein the conveying mechanism further includes: a stopper attached to the arm unit; and a rotational-force-applying unit that includes an engaging portion that becomes engaged with the stopper when the arm unit retracts and that applies a rotational force for retracting the arm unit; wherein a pushing force applied to the recording medium by the aim unit when the movement of the arm unit is restricted is set to be smaller than a frictional force applied to the recording medium when the recording medium is ejected through the slot; wherein the rotational-force-applying unit applies the rotational force to the arm unit such that the engagement between the stopper and the engaging portion is canceled when the recording medium is pulled out from the slot.
