摘要
We developed fabrication process using "all spin method" for dual layered Blu-ray Disc ROM. All of the light transmitting layer consisting of a space layer, a cover layer and a hard coat are formed by spin-coating method. Regarding the cover layer, the cycle time is less than 15 seconds and the efficiency of usage of the UV curable resin is 59%. The fabricated disc has sufficient property of thickness variation of the light transmitting layer for all disc area. The disc also has good performances of tilt characteristics including tilt transition caused by environmental sudden change due to the moisture control layer although the substrate material is conventional poly-carbonate. We confirmed the feasibility of the dual layered BD-ROM by "all spin method" and it shows the possibility of low cost BD-ROM disc.
