In an optical recording medium consisting of an optical recording medium, there are vent holes that communicate the air layer with the surface near the center hole of each disk substrate, and ventilation holes that are installed at the center of both sides of the medium and that allow air to pass through the surface of the disk substrate when the medium is not in use. block the stomata,
It has a pair of magnetic bodies connected by an elastic body that opens the ventilation hole when in use, and a continuous or intermittent annular protrusion with a height greater than the thickness of the magnetic body, with the annular protrusion facing the disk substrate. . An optical recording medium, comprising a pair of resin hubs that are bonded to the center of the disk substrate with the magnetic material housed inside.
