In the Micro-Reflector recording, light beams are irradiated on both sides of the recording medium. Two light beams are then interfered on the recording layer by aligning their focal points, thereby recording an interference fringe which corresponds to 1-bit information capacity. The information is reproduced by emitting light on the front side of the medium. Interference fringes with different depths can be recorded by changing the depth of the focal points as in the case of recording on a multilayered medium.Micro-Reflector isn't without its problems. Along with slow data transfer rates, Sony has found that when recording to deeper layers, the signal gets weaker. Once Sony resolves these problems, they plan to introduce 20 layer discs with a total capacity of 500GB. If you'd like to read more, Tech-On's entire report can be found here. Add a comment
In addition to multilayer recording, the company points out advantages in that the method is less likely to be influenced by the expansion/contraction of photopolymer due to heat, thus preventing signal reading errors. This is because the interference fringes are smaller than those used in other holographic recording methods where recording is performed on a page basis. The company expects that the Micro-Reflector system will easily facilitate reductions in equipment cost because it can utilize existing blue-violet semiconductor laser diodes and eliminate the need of a spatial phase modulator, CMOS sensor or other parts.

Optical and magnetic storage manufacturer Moser Baer India has developed the world’s first high speed 8x Blu-ray disc (BDR), which is a major advance in next generation optical media formats. The 8x Blu-ray disc (BDR) technology has been jointly developed with newly acquired OM&T, the former R&D subsidiary of Philips.No word on pricing or availability. As we find out more, we'll let you know. In the mean time, Moser Baer's entire press release can be found here. Add a comment
With the latest development, end users will be able to have a faster media that can record a 2-hour transmission equivalent of HD (High Definition) quality data in less than 15 minutes. The next generation formats have a capacity ranging from 15 GB to 50 GB and offer over five to ten times the data storage capacity of standard DVD media. These next generation formats are best suited for reliable business backup, such as medical and government imaging, photography, videography, as well as high definition video recording.

Ritek on May 21 announced it has received the certification for both HD DVD-R (recordable, write once) and HD DVD-RW (rewritable) formats, becoming the only Taiwan-based producer of optical discs to receive certification.The article also mentions that volume production of the two formats will begin during second half of this year at the earliest. If you'd like to read more, head on over to DigiTimes. Add a comment
The technological barrier for HD DVD-R is quite high and that for HD DVD-RW is higher, Ritek indicated. Ritek's manufacturing capability for DVD+R/-R DL (single-sided double-layer) discs was helpful in obtaining the certification, the company pointed out.

The hitachi, ltd. Research Center (chief: Yasushi Hukunaga/below, Hitachi), this each time, basic technology of the optical system which expands the regenerative signal output of the optical disk in 10 times was developed. As for this technology, it is something which makes the optical detection method which expands the regenerative signal making use of the interference of two lights the optical disk apply. With this technology, reflected light of the optical disk being weak, accurate reading of the regenerative signal becomes possible, you say that reflected light becomes weak by the fact that the number of record layers increases fundamental topic of the multilayer optical disk is solved, the blue ray disk whose record playback of the single sided 100~200 gigabyte is possible at 4~8 layer (Blu-ray Disc) actualization of the device is expected.While details are sketchy due to the translation, Hitachi appears to be splitting the laser in half to create a reference beam. This second beam helps cut through the interference caused by the layers being so close to each other. According to other, unconfirmed sources, Hitachi plans to bring this 200GB disc to market by 2009. If you'd like to read more, their entire press release can be found here. Add a comment

While ATAPI has been popularly used in optical disc drives (ODDs), SATA (serial ATA) stands a good chance of replacing the former as the mainstream interface standard for DVD-ROM drives and DVD burners in the second half of 2007 due to increasing adoption of the latter by global OEM/ODM clients such as Dell and Hewlett-Packard, according to ODD makers in Taiwan.While this isn't the first time DigiTimes has made these claims about SATA, ATAPI drives are definitely on the way out. If you'd like to read more, head on over to DigiTimes. Add a comment
Many international OEM/ODM clients have requested for use of SATA in place of ATAPI for new DVD-ROM drive and/or DVD burner models sent for product certification over the past four months, the sources pointed out. As a result, the total shipment volume of SATA DVD-ROM drives and DVD burners is likely to exceed that of ATAPI models in the second half of the year, the sources indicated.

Gigastorage, a second-tier maker of optical discs in Taiwan, early in May started volume production of CD-R discs at an initial monthly capacity of two to three million discs in Thailand, and will begin volume production of photovoltaic conductive paste, its new product, in July of 2007, according to the company.If you'd like to read more, head on over to DigiTimes. Add a comment
Gigastorage completed its shift of CD-R disc manufacturing equipment from Taiwan to its factory in Thailand and then began production. While the factory's production will focus on CD-R discs for the time being, Gigastorage may also shift production lines of DVD+R/-R discs from Taiwan if demand in the ASEAN (Association of Southeast Asian Nations) market grows to a certain level, the company indicated.

In the Taiwan retail market, small brands or brands without a reputation have recently provided a large volume of DVD+R/-R discs of which purchasers have found as many as 30-50% failed in performance. Such defect rates are historically very exceptional, according to Taiwan retail channels.These failure rates are quite high, even for low grade media. Nevertheless, people shouldn't be surprised by the quality. As the old saying goes, you get what you pay for. If you'd like to read more, head on over to DigiTimes. Add a comment
Currently, DVD+R/-R discs supplied by international brands, including Philips, Sony and TDK, sell at NT$8-12 (US$0.24-0.36) per disc while small or little-known brands charge only NT$6-7 for a disc, the sources indicated.
