In the initialization of an information layer with a burst cutting area (hereinafter referred to as “BCA”), at least one of the initialization conditions including a laser power, a linear speed, and a focal point of the laser beam for the information layer is changed between the BCA region and a data area that is an area for recording and reproducing information. In the initialization of an information layer without the BCA, at least one of the initialization conditions including a laser power, a linear speed, a focal point of the laser beam for the information layer and a feed pitch is changed between the area corresponding to the BCA and the area corresponding to the data area.

摘要： In a multilayered recording medium, when a titanium oxide layer is formed using a sheet-type sputtering device, a transmittance significantly varies due to variations in thickness of the titanium oxide layer. Therefore, according to the present invention, in the multilayered recording medium having the titanium oxide layer, a second dielectric layer composed of titanium oxide, or mainly composed of the same, is formed on a first dielectric layer composed of niobium oxide or silicon dioxide, or mainly composed of the same. Further, when the sheet-type sputtering device is used, at least one chamber for promoting removal of water and oxygen from a substrate is provided between a load lock chamber and a chamber for forming a transmittance adjustment layer.
