Abstract: Provided is an apparatus and method of initializing a recording layer used in manufacturing a phase-change optical disk for storing information. The optical disk (200) is initialized using a UV lamp (110) in order to initialize the recording layer of the phase-change optical disk (200) capable of repeatedly writing information, without a separate optical head, whereby it is possible to increase productivity by remarkably reducing an initialization time of the optical disk since a large area is initialized using a UV beam. The recording layer may have a main component made of at least one selected from a group consisting of Ge, Sb, Te, In, Sn and Ga, and an additive made of at least one of Ag and Bi.
