摘要： The present invention provides a method of reading information from a luminescent data storage medium comprising Al 2 O 3 . The luminescent material is a single crystal of Al 2 O 3 comprising a first dopant of magnesium and a second dopant comprising carbon wherein the material includes at least one type of oxygen vacancy defect. The disclosure relates to writing and erasing of the information using photoionization via sequential two-photon absorption and non-destructive reading the information using one-photon absorption and confocal fluorescent detection. The apparatuses for writing and reading the information incorporate confocal detection and spherical aberration correction for multilayer volumetric fluorescent data storage. The methods also allow multilevel recording and readout of information for increased storage capacity.

摘要： A recording medium includes a first substance and a second substance at least in which the first and second substances undergo an oxidation-reduction reaction when an external energy is applied, thereby recording information by varying the optical characteristics. In the recording medium, the reaction of the first and second substances is suppressed, reaction which degrades the recording characteristics other than the case where the recording medium is subjected to recording. In an optical disk 100 (i.e., the recording medium), a WO3 film 2 (i.e., a second substance), a C film 3 (i.e., a third substance) and an Sn-10 atomic % Sr film 4 (i.e., a first substance) are formed successively on a substrate 1. When the recording medium is irradiated with a recording laser beam as a external energy, the WO3 forming the film 2 is reduced to WO2.83, and the Sn-10 atomic % Sr forming the film 4 is oxidized to SrO and/or SnO mainly with the WO3 and the Sn-10 atomic % Sr passing through the C film 3 and/or destroying the C film 3. When the recording medium is not irradiated with the recording laser beam, the presence of the C film 3 suppresses the reaction between the WO3 film 2 and the Sn-10 atomic % Sr film 4.
