摘要： A method of manufacturing an optical disc comprises the steps of: (1) forming a substrate including an inner supporting section and an outer information recording section, the inner supporting section having a thickness larger than that of the outer information recording section; and (2) forming a vibration suppressing layer by printing UV curable paste three to five times over the surface of the non-recording side of the outer information recording section from an inner edge of the outer information recording section to a designated diameter, wherein the printed UV curable paste has a weight of 15% to 25% of the weight of the substrate, and at least 90% of the weight of the printed UV curable paste is distributed within a circular region with diameter 90mm to 110mm, each time the UV curable paste printed not exceeding 5% of the weight of the substrate.

摘要： An optical disc of a thicker supporting section and a thinner recording section inludes a reinforcement section of a predetermined width which overlaps a supporting section and a recording section. The reinforcement section strengthens the structure of the optical disc and raises the resonant frequency of the optical disc, so that the vibration of the optical disc is suppressed, thus making the disc suitable for high speed (16x up) reading/writing. The optical disc comprises: a circular opening disposed in the center of the optical disc; an annular recording section for recording information; an annular supporting section disposed between the annular recording section and the circular opening, wherein the annular supporting section is thicker than the annular recording section; and an annular reinforcement section which is disposed on one of the two sides of the optical disc and overlaps the annular supporting section and the annular recording section

摘要： An optical disc includes a round opening at the center of the optical disc, an annular recording section configured to record information, an annular supporting section between the round opening and the annular recording section and configured to support the optical disc, and a spoiler provided on a non-read/write side of the annular recording section and configured to disturb the flow field inside the optical disc drive when the optical disc is rotating, the spoiler having a centerline average roughness between 2 μm and 10 μm, a thickness between 0.02 mm and 0.05 mm, an area occupying at least 5% of the non-read/write side. The flow field so disturbed changes from a laminar state to a turbulent state and thus the read/write characteristics of the disc is improved due to lower air resistance experienced by the rotating disc.
摘要翻译：光盘包括在光盘中心的圆形开口，被配置为记录信息的环形记录部分，圆形开口和环形记录部分之间的环形支撑部分，并被配置为支撑光盘，以及设置在环形记录部分的非读/写侧，并且被配置为当光盘旋转时干扰光盘驱动器内的流场，扰流板的中心线平均粗糙度在2μm和10μm之间，厚度在0.02mm之间和0.05mm，占据非读/写侧至少5％的面积。如此受干扰的流场由层流状态变化到湍流状态，因此由于旋转盘所经受的较低的空气阻力而改善了盘的读/写特性。
