摘要： A disk drive apparatus includes a casing having an upper plate; and a tray. The upper plate includes an arm having an attracted member fixed thereto. When the tray moves from a protruding position to a recording-and-playback position, since engagements of the arm and the tray are engaged with each other, the main body of the arm swings, and the attracted member serves as a chucking position facing a chucked portion of the disk-shaped recording medium placed on the tray. When the tray moves from the recording-and-playback position to the protruding position, since the engagement of the arm is detached from the engagement of the tray, the main body of the arm swings, and the attracted member serves as a retracting position retracting above the chucked portion of the disk-shaped recording medium.

摘要： A disk drive unit advantageously prevents dust from adhering to a pickup. The disk drive unit has a housing and a tray. The tray reciprocates between a retracted position and a projected position. A first pickup and a second pickup have a spindle motor located therebetween. The tray has a first cutout and a second cutout. A cover is provided to cover the top of the second pickup in its retreated position. The cover has a cover piece, which is disposed in a front portion of the cover that is positioned on the upstream side relative to the rotational direction of a disk-shaped recording medium such that it is movable in a direction parallel to the direction in which the second pickup moves, and urged in the projecting direction.
摘要翻译：磁盘驱动单元有利地防止灰尘粘附到拾取器上。磁盘驱动器单元具有外壳和托盘。托盘在缩回位置和突出位置之间往复运动。第一拾取器和第二拾取器具有位于其间的主轴电动机。托盘具有第一切口和第二切口。提供盖子以覆盖其处于退回位置的第二拾取器的顶部。所述盖具有覆盖件，所述盖件设置在所述盖的前部中，所述盖部位于相对于盘状记录介质的旋转方向位于所述上游侧的位置，使得其能够沿与第二拾取器移动并沿着投影方向被推动。

摘要： In a disc cartridge, the shutter opening/closing operation is to be performed reliably. To this end, the distal ends of a first engagement member 75 and a second engagement member 79 provided to a base 66 are pivotally movable in a direction along a lateral surface of a housing 51, in addition to being movable in a direction perpendicular to the lateral surface of the housing 51. The state of engagement of the first engagement member 75 and the second engagement member 79, provided to the base, with a first mating engagement section 110 and with a second mating engagement section 108, provided to an inner rotor 101, facing outwards from one lateral surface of the housing 51, when the base 66 performs relative movement along the lateral surface of the housing 51, may be maintained for prolonged time, while the load applied to the distal ends during engagement and disengagement may be reduced.
