摘要： A high-definition and high-precision optical disc medium suitable for high density includes a recording layer which has an inner peripheral region extending radially outwardly from a central bore to a signal start boundary and a signal region extending radially outwardly from the signal start boundary. A light transmitting layer is disposed on the recording layer and the signal region of one face of the recording layer adjacent to the light transmitting layer occupies a laser beam incident face such that either reproduction or recording and reproduction of information is performed from the recording layer via the light transmitting layer. The inner peripheral region of the face of the recording layer is formed flat and a recess is formed, on one face of the optical disc medium opposite to the light transmitting layer, in an area corresponding to the inner peripheral region of the recording layer.
