ことを特徴とする光デイスク。[Scope of Claim for Utility Model Registration] Two magnetic members for a magnetic clamp each having a boss protruding from one side of a disk are inserted into a center hole of a disk substrate from both sides, and the tips of the bosses are aligned with each other. In an optical disk that is butted together and fastened together, the magnetic member is formed so that the total height of both boss portions is slightly larger than the thickness of the disk substrate, and an engaging protrusion is provided in the radial direction of the magnetic member. and an engagement groove provided on the disk substrate corresponding to the engagement protrusion are fitted so that the magnetic member cannot rotate relative to the disk substrate. .
