ABSTRACT:
In an optical disk according to the present invention, a part of a disk is heat pressed to thereby connect a clamping plate to the central part of the disk. The heat pressed part of the optical disk is heat pressed into a discontinuous form during connection of the clamping plate to the disk. An apparatus for manufacturing such an optical disk connects the clamping plate to the disk by heat pressing a part of the disk onto which the clamping plate is mounted. This is carried out by a pressing surface of a heat press member. The heat press member is provided in its annular pressing surface with radially elongated grooves, so as to divide the annular pressing surface into a plurality of portions by the grooves.
