Patent ID: 7813258

Claim:
A method for reproducing information as recorded data on a medium comprising the steps of: providing the medium, the medium having pits on a substrate and a second film, wherein a super-resolution material is embedded in the pits; reproducing information by irradiating a light beam on the medium; wherein the super-resolution material and the second film do not have a super-resolution effect when the light beam with a first power level is irradiated on the medium, and both the super-resolution material and the second film have the super-resolution effect when the light beam with a second power level being higher than the first power level is irradiated on the medium; wherein a readout signal level derived from the light beam with the second laser power level on the pits is lower than a readout signal level derived from the light beam with the first power level on the pits; and wherein a readout signal level derived from the light beam with the second laser power level on a non-pit area is higher than a readout signal level derived from the light beam with the first power level on the non-pit area.
