description | A method for preventing optical disc from damage includes stopping driver's driving if optical disc input end region can not fetch information normally at that speed when optical disc is started to rotate on certain speed; waiting till optical disc rotating speed is up to certain speed if said input end region can fetch information normally, judging whether said input end region can fetch information normally within set period or not, determining that optical disc is damaged if it can not fetch information normally within set period and stopping driver's driving. |
