A method for detecting the obliquity of an optical disc drive is provided. The method includes the steps of calibrating balance gains of TE signals and CE signals with predetermined obliquities of the optical disc drive, curve-fitting and storing a relating function between the predetermined obliquities and the balance gains, calibrating the balance gains of signals for an installed optical disc drive, and acquiring an calibrated balance gain to find the obliquity of the optical disc drive from the relating function. |
