Abstract

PURPOSE:To increase recording capacity by laminating at least two layers of laminates of signal recording layers recorded with the signals modulated by an information signal as bit arrays on at least one face and sheet materials and forming one layer of reflecting layer. CONSTITUTION:The respective signal recording layers 14-16 transferred and formed with the signal bits 14a-16a are laminated respectively on the sheet materials 17. These laminates are further laminated and the reflecting layer 13 consisting of aluminum, etc., is formed on the rear face of the sheet material 17 of the laminate on the lower layer side. A disk substrate 12 is superposed thereon, by which a sheet of disk 11 is formed. The disk 1 is made into multi- layered structure in such a manner and one layer of the reflecting layer 13 is provided, by which the signal recording capacity can be increased according to the number of the signal recording layers. The disk having the high information capacity is thus obtd.
