Abstract
An adjusting method for a synchronous signal in an optical storage device is disclosed. The optical storage device produces a predetermined synchronous signal, and the predetermined synchronous signal normally is matched with the data synchronous signal of the data on the optical disc. The predetermined synchronous signal includes a number of predetermined synchronous impulses, and the data synchronous signal includes a number of data synchronous impulses. In the method, when the data synchronous signal is not matched to the predetermined synchronous signal, it is searched that whether or not a data synchronous impulse is outside of the predetermined window and another consecutive data synchronous impulse detected later by a distance of an image frame is detected. Also and, according to the data synchronous impulse, the predetermined synchronous impulse is adjusted, so that the data synchronous impulse is matched with the predetermined synchronous impulse. The method can improve the function to successfully read the optical disc having the data gap.
