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 [mu]m and 10 [mu]m, 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.
