Abstract
A method for reproducing information recorded on a disc is provided. In the method, a reproduction signal is irradiated towards the disc to produce a corresponding read signal. Also, the reproduction signal is positioned at a first position within a non-program area of the disc and is attempted to be focused on the disc. If the reproduction signal is focused on the disc, the method determines if the read signal has a valid signal level. If the read signal does not have the valid signal level when the reproduction signal is positioned at the first position, the reproduction signal is moved to a second position within a program area of the disc while the reproduction signal remains focused on the disc. Then, the method determines if the read signal has the valid signal level when the reproduction signal is positioned at the second position. Also, a disc player that employs the method and a software program that instruct a controller to perform operations in accordance with the method are also provided.
