title: Improved mastering material for multilevel blue laser disc.
abstract: In order to get a small-sized pit, the reaction threshold of a photoresist is enhanced by increasing the prebake temperature and time. With the improved photoresist, a pit size corresponding to or even smaller than the minimum pit on a blue laser disc can be obtained on an industrial DVD product line. The improved photoresist may serve as the master material of future multilevel blue laser discs, which might provide a potential solution for the fabrication of multilevel blue laser discs.
