<p>The optical storage medium (1), in particular a read-only optical disc, comprises a substrate layer (2), a read only data layer (3) comprising a pit structure and being arranged on the substrate layer (2), a mask layer (4) comprising nanoparticles for providing a super resolution near field effect, and a dielectric layer (5) arranged between the data layer (3) and the mask layer (4). The dielectric layer (5) has a thickness (9, 10, 12, 13), which changes in dependency of the pit structure and is for example a plastic layer having a completely flat surface for providing a uniform arrangement of the nanoparticles. For the manufacturing of a respective optical storage medium, the dielectric layer (5) is arranged on the data layer (3) advantageously by means of spin coating.</p> |
