PURPOSE: Optical recording media is provided to confine scratch generation on a surface by forming a hard coating layer and enhance the repetition property of recording/deleting by including an interface layer. CONSTITUTION: Optical recording media(400) comprises a substrate(410), wherein a plurality of protrusions(430) are formed on the outer circumference of the substrate, each protrusion has an island pattern, the width of the protrusion is 180~200μm, the length of the protrusion is over 0 and 1.1mm or less and the thickness of the protrusion projected from the outer circumference of the substrate is 40~80μm. |
