| 20100107183 | OPTICAL DISC HAVING GAS FLOW SPOILER AND THE METHOD FOR FABRICATING THE SAME - 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. | 04-29-2010 |
