Abstract

An annealing method is provided in which the time required for annealing treatment of photo disk is reduced to 1/8 of the time in prior art, the mechanical properties being raised, the electrical properties being nothing worse than that of prior art. A plate is heated within an annealing furnace to a predetermined temperature, and the opposite side of the recording face of a photo disk is contacted on the plate so heated such that heat of the plate is directly transferred to the photo disk. In this state, the plate is again placed into the furnace for predetermined period, then the plate, maintained in the state contacting with the photo disk, is pick up and naturally cooled.
