ABSTRACT:
An optical-information recording medium includes a substrate that includes a servo surface; an information recording layer laminated on the servo surface of the substrate capable of recording information as a hologram produced by interference between an information beam containing the information and a reference beam; a tracking servo area that is formed in a track direction on the servo surface, and that records therein tracking information for tracking servo control; and a following up servo area that is formed in the track direction on the servo surface, and that is to be irradiated by a beam emitted from an optical-information recording apparatus for recording the information in the information recording layer so as to make the beam follow a rotation of the optical-information recording medium.
