Abstract
A reproduction power test method for setting an optimal power of a reproduction light beam for reproducing an information from a domain wall displacement type magneto-optical medium comprises the steps of detecting a domain wall displacement start reproduction power Pr at which the domain wall starts to be displaced, and a maximum reproduction power Pr allowing the domain wall displacement, and determining an optimal reproduction power Pr using a previously obtained relational expression whereby Pr , Pr and the jitter characteristics of a reproduced signal are optimized.
