A method and device are disclosed for improving reliability of reading an optical storage medium, such as an optical disc (20). A disc spin speed value (31) of the optical disc (20) is provided and an unnormal value of said disc spin speed value (31), which differs from a disc spin speed value within a range of nominal disc spin speed values, is detected, indicating normal spinning operation of said optical disc (20). By using this method, the spinning loss of an optical disc, e.g. due to insufficient disc clamping force, is detected fastly and reliably, in a manner resulting in a reduced risk of damaging the disc and disc reader during such spinning loss. Further actions may be taken in both cases, including disabling the drive in order to prevent damage of the disc or to thwart such illegal usage.
A method of improving reliability of reading an optical storage medium (20), said method comprising
An optical storage medium reading and/or writing apparatus (10) having improving reliability of reading from or writing to an optical storage medium, said apparatus comprising
A computer-readable medium (70) having embodied thereon a computer program for improving reliability of reading from and/or writing to an optical storage medium, for processing by a computer (29), the computer program comprising
