发明名称 OPTICAL RECORDING MEDIUM
摘要 An optical recording medium having friction characteristics(friction force and/or friction coefficient)reduced on the surface of an optical recording medium,especially on the surface of a light transmitting layer or a hard coat layer.An optical recording medium which comprises a substrate(11),a recording layer(13)provided on the substrate(11),and a hard coat layer(15)provided on the recording layer(13),and which records/reproduces data by applying a laser beam onto the recording layer(13)via the hard coat layer(15),wherein a friction coefficient measured is up to 1.5 when a planar weight of 5−50 g/cm<sp>2</sp> is applied to the surface of the hard coat layer(15)via a self−adhesive type long−fiber nonwoven fabric mainly containing cellulose while the optical recording medium is turned at 50−3000 rpm.Accordingly,a flaw on the surface of a translucent substrate serving as a light incident surface can be effectively prevented.
