<p>The optical storage medium comprises a substrate layer (2), a read-only data layer (3) with data arranged in tracks on the substrate layer (2), a protection layer (4a) and a nonlinear layer (4b) disposed on the data layer (3), wherein the nonlinear layer (4b) comprises a super- resolution material having an increased reflectivity when irradiated with a laser beam, the protection layer (4a) and the nonlinear layer (4b) constitute an anti-reflective layer (4) and wherein the optical storage medium does not include a reflective layer. The optical storage medium is in particular essentially transparent for light intensities being below a super-resolution threshold of the super-resolution material and has a low reflectivity factor for reducing noise and crosstalk.</p> |
