ABSTRACT:
A high-density optical recording medium and method of recording data on the optical recording medium. The optical recording medium includes a plurality of data recording/reproducing surfaces having reflectances for light passing through a pit area, a land/groove area, and a land/groove area on which data are recorded, of a data recording/reproducing surface included between a light source for emitting light and a recording/reproducing surface selected from the plurality of data recording/reproducing surfaces, the reflectances satisfy the expressions r1≧r2≧r3and {(r1−r3)/r1}≦0.2, where r1, r2and r3are the reflectances of the pit area, the land/groove area and the land groove area on which data are recorded, respectively.
