A method of selecting laser beam in an optical disk drive is disclosed. A first laser beam (such as CD laser beam) is used to read an optical disk and generate a first testing result. Whether the first testing result is normal is then determined. The first laser beam is used to read data from the optical disk if the first testing result is normal, and a second laser beam (such as DVD laser beam) is, in stead, used to read data from the optical disk if the first testing result is abnormal.
