Expanding the Blu-ray Disc (BD) Lineup
4X Recordable and Single-sided Double-layer Recordable Discs
Compatible with Inkjet Printers |
|
| Mitsubishi Kagaku Media Co., Ltd. |
|
Mitsubishi Kagaku Media Co., Ltd. (Head offices: Minato-ku Tokyo; President: Shigenori Otsuka) is extending its lineup of Blu-ray Disc (BD) products. A total of nine new products to be released in series are all compatible with inkjet printer*1. The 2X recordable BD (BD-R) and the rewritable BD (BD-RE) will go on sale from early October, and the 4X BD-R and the single-sided double-layer (DL) 2X BD-R will launch from early November.
Mitsubishi Kagaku Media has perfected its spin coating process*2 that is used to form cover layer so that it is now possible to achieve a surface smoothness to the order of just one hundredth of a micron, regarding the 4X BD-R, which records at high speed, and the BD-R DL, which has a 50GB capacity. As a result, the performance of the servo*3 is also considerably improved, which in turn now allows for stable recording even at high speeds. In addition, a newly-developed hard coat layer has been added to all of nine new products, leading to greater durability and improved performance.
With the spread of high-vision digital broadcasting, the standard of compatible devices that can maintain the image quality of the high-vision broadcasts has also increased. On the other hand, the quantity of digital data for storage, such as with high resolution digital cameras, is also rapidly increasing; to meet the dawning of this new era in digitalization, Mitsubishi Kagaku Media has extended its available range of choice for BD products, which are able to record and store large amounts of data.
The Mitsubishi Kagaku Media/Verbatim Group aims to become a recording media company that continues to create new values demanded by the time.

| [Characteristics of Mitsubishi Kagaku Media's BDs] |
|
 |
|
|
• Recording Surface on BD-R Made with unique MABL (Metal ABlative Layer)
On the recording surface's MABL (Metal ABlative Layer), made with Mitsubishi Kagaku Media's own unique ablative method using a special metal nitride, pits are formed through the breakdown of the recording surface's material. As the metal nitride is chemically more stable than metal alone, the disc's storage capability over the long term is comparable to the highly-reliable AZO recording dye films; furthermore, it achieves an extremely wide power margin, which makes it difficult for the recording to be affected by fluctuations and variations in the drive's recording power.
• Mitsubishi Kagaku Media's Own SERL (Super Eutectic Recording Layer) Film on the BD-RE
The rewritable BD-RE uses the SERL (Super Eutectic Recording Layer) technology, developed in-house at Mitsubishi Kagaku Media, for its recording film. Ever since Mitsubishi Kagaku Media was the first company in the world to apply this recording layer technology to its 12X CD-RW, it has become a standard in high-speed, durable rewritable optical discs. Like the BD-R, the BD-RE boasts an extremely wide power margin, its recording properties remain stable over a long period of time, and its advanced durability makes it suitable for repeated recording and playback.
• Advanced Surface Protection Layer (Cover Layer, Hard Coat Layer)
Mitsubishi Kagaku Media has developed a protective layer for the disc surface by making optimum use of its capabilities in creating hybrid organic and inorganic coating materials. The protective layer is highly resistant to scratches, dirt and fingerprints. As a result, users can safely use these discs even without a cartridge case. In particular, a novel cover layer has been applied to the 4X BD-R and the 2X BD-R DL discs, making them even less likely to attract dirt. A newly-developed hard coat layer has been added to all products*, leading to greater durability and improved performance (easier to wipe clean compared to conventional hard coat layer).
*Excluding the DBR25N1, DBE25N1, VBR130N1, VBE130N1.
• Precise Spin Coating Method
Mitsubishi Kagaku Media's own precision spin coating method has been adopted in the manufacture of the cover layer and hard coating. This has achieved an extremely uniform thickness across the whole layer to within?1?m. For the 4X BD-R and the 2X BD-R DL discs, an even more advanced spin coating method was used, creating a surface smoothness of 1/100 micron order. As a result of this, the characteristics of the servo are also greatly improved, and stable data transfer can be attained even at high recording speeds.
• High Precision Mastering Technology
Mitsubishi Kagaku Media has also made excellent use of its high precision mastering technology that it has built up over the years. Compared to DVDs, BDs require a narrower track pitch in the grooves in order to raise the recording density (0.74?m for DVDs, 0.32?m for BDs). Besides developing a deep UV laser exposure device, by optimizing its mastering process, Mitsubishi Kagaku Media achieved ultra fine recording grooves on its BDs as a result of optimizing its already advanced mastering process.
• Inkjet-compatible Label
The same "double-layer ink reception layer" used on Mitsubishi Kagaku Media's inkjet-compatible DVD series has also been adopted on its Blu-ray disc series, which means that the ink will dry quickly and fix well. Not only can the labels be printed on with normal household inkjet printers, but they can also be handwritten with oil-based or water-based ink pens. The labels are white, so the printing stands out clearly.
