    • An optical disc drive (2) for optical discs (9), comprises a retractable disc tray (1) with an opening (3) and a tray base (33) on which a disc (9) with non-circular shape can be placed and centered by a user when the tray (1) is in a deployed position. A shaft (30) with drive plate (31) and centering pin (32) is able to rotate the disc (9) when the tray (1) is in a retracted position during operation of the drive (2). The drive comprises first means (25, 27) arranged on the shaft and second means (26, 28) arranged around the shaft, the first means and the second means being able to interact with each other, and to stop the rotating shaft (30) in a predefined end position. Alternatively the drive (2) comprises means (11, 12, 14, 15) for determining the relative orientation of the disc (9) with non-circular shape in relation to an absolute rotation angle of the shaft (30) bearing the disc (9), in order to enable the drive (2) to rotate the shaft (30) with disc (9) into a position, in which the tray can be safely deployed.
    • 一种光盘驱动器(2)的光盘(9)包括一个可伸缩的盘片托盘(1),其具有开口(3)和托盘底座(33),其上的盘(9)具有非圆形形状可放置 和由用户为中心的当托盘(1)是处于展开位置。 的轴(30)与传动板(31)和定心销(32)能够旋转盘(9)当式(1)的托盘是在驱动器的手术期间缩回位置(2)。 驱动器包括布置在所述轴和围绕轴设置的第二装置(26,28),所述第一装置和第二装置是能够彼此相互作用,并停止所述旋转轴的第一装置(25,27)(30 )在预定义的结束位置。 可替代地,驱动器(2)包括装置(11,12,14,15),用于确定的采矿盘(9)相对于非圆形形状的相对定向(在轴承盘中的轴(30)的绝对旋转角 9),轴(为了使驱动器(2)与光盘旋转30)(9)到其中托盘可以安全地部署的位置。
