摘要： An optical disk recording medium includes a single layer disk substrate having a hub provided on one side which includes a circular magnetic plate for effecting chucking of the optical disk. On the opposite side of the disk substrate a reinforcing plate is attached for reducing disk warpage during chucking, loading etc. The circular magnetic plate includes a centering opening for disk chucking, while a center opening of the reinforcing plate is larger in diameter than the centering opening. The reinforcing plate covers a central opening formed in the disk substrate and includes a boss portion which is projected into the opening. A groove is provided in the reinforcing plate at the outer circumference of the boss portion for retaining excess adhesive when the substrate is affixed to the reinforcing plate.

摘要： A recording layer 6 records and stores information and comprises a plurality of layers, namely a first layer 6a and a second layer 6b. The first layer 6a is made from a recording material which gives parallel directions to saturation magnetization and sublattice magnetization. The second layer 6b is made from a recording material which gives antiparallel directions to saturation magnetization and sublattice magnetization at room temperature. The recording material for the second layer 6b gives parallel directions to saturation magnetization and sublattice magnetization at around a read temperature.
