摘要： In an optical disk drive device, in order to reduce structural vibration noise and aerodynamic sound during high-speed revolution, a recess is formed at the deeper end. This recess is in a position axially symmetric to a hole for the movement of an optical head with respect to the axis of a spindle motor, and its size is substantially equal to that of the movement hole. This recess serves to suppress the vibration mode of a disk tray and the air flow between the disk and the disk tray. Noise is reduced even when the disk is turning at high speed.
摘要翻译：在光盘驱动装置中，为了在高速旋转期间减少结构振动噪声和空气动力声，在较深的端部形成凹部。该凹部处于与孔相对于主轴电机的轴线移动的孔的轴向对称的位置，并且其尺寸基本上等于运动孔的尺寸。该凹部用于抑制盘托盘的振动模式和盘与盘托盘之间的空气流动。即使磁盘高速转动也会降低噪音。

摘要： A disk drive device has a configuration in which one of stepped parts defined by a circular recess for guiding a disc, formed in a disc tray is substantially flush with the bottom surface of the circular recess even in an area beyond the outer peripheral part of a disc so that no air cavity part facing the outer peripheral side surface of the disc is induced around the disc. Thereby, it is possible to aim at lowering cavity noise caused by the air cavity during high speed rotation and fluid noise caused by turbulence.
