In this study, a commercial BD (Blu-ray disc) and BD optics (blue laser and NA0.85) were used for multilevel recording. The goal is to double both the present capacity and data transfer rate. To achieve this, it is necessary to overcome severe inter-symbol interference (ISI) from outer cells at a small cell length. In order to suppress ISI, we have developed an advanced data detection method that uses CBDD (Cell Boundary Data Detection) and TCM (Trellis-Coded-Modulation), and have achieved an areal density of 34.6-Gbit/in2 multilevel recording.

In this work, the crystallization characteristics and recording mechanism of a-Si/Ni bilayer recording film under thermal annealing and pulsed laser irradiation are investigated. The optical properties of the a-Si/Ni bilayer recording film before and after annealing were measured. In addition, the dynamic test was conducted to evaluate the potential of the a-Si/Ni bilayer for use in the write-once blue-ray disk

Fourth-generation technologies that use multiple layers are now under investigation. This presentation describes the inter-layer interference and crosstalk characteristics of multiple layers under several illumination conditions using Babinet decomposition of the recording structure. Limitations based on performance bounds are introduced for various film characteristics, like reflectivity, transmission and layer spacing. Primary results include that the total crosstalk is minimized for certain layer spacings for both coherent and incoherent illuminations. The incoherent illumination shows lower values of total crosstalk and more generous tolerances than the coherent illumination
