| titleOfInvention | High data capacity storage medium with protection code, method for obtaining the protection code and respective data reading apparatus |
| abstract | The optical storage medium comprises a substrate layer, and a data layer disposed on the substrate layer, the data layer comprising data being arranged in tracks as marks and spaces. A protection code is coded in one of the tracks or a part of a track which code comprises marks of a first size and marks of a smaller, second size. The marks of the second size have in particular a width being smaller than the width of the marks of the first size. To obtain the protection code, a method is used comprising the steps of reading a track or a part of a track with a first laser power for obtaining a first data signal, reading the same track or the same part of a track in another step with a second laser power being different from the first laser power for obtaining a second data signal, and calculating the protection code by taking into account the first and the second data signals. The protection code may be calculated for example by a microprocessor of a respective data reading apparatus. |
