An optical disc wherein recording can be performed on a label plane even only by an optical disc recording/reproducing device using a direct-current motor as a power supply of an optical pickup in a traverse direction. The optical disc is provided with a visible information recording layer (207), which can record visible information by changing a physical structure by irradiation light of the optical pickup, and a radius position information recording part (201). Therefore, even when an optical disc recording/reproducing device using a direct-current motor as a power supply of the optical pickup in the traverse direction, the contents of the radius position information recording part (201) are read and recorded on the label plane only by the device.
