Earlier this month, Sony was sued by a California company called Target Technology. According to Ars Technica, Target Technology claims that the Blu-ray discs manufactured by Sony infringe upon a patent it owns for reflective-layer materials used in optical discs.
Target Technology, a company that manufactures and sells thin film alloys for optical discs, has sued Sony in the US District Court for the Southern District of Indiana for violating a patent it holds on reflective layers used in optical storage media. The patent in question, no. 7,018,696, was filed for in April 2004 and issued in March 2006.

Target Technology's complaint doesn't go into detail on exactly how Blu-ray infringes on its patents, but alleges that all Blu-ray discs manufactured, sold, and marketed by Sony are infringing. Target Technologies is demanding a jury trial, a declaration that the patents are valid and enforceable, damages, and an injunction barring Sony from future infringement.

DigiTimes has reported that support for HP's LightScribe technology is on the decline. According to their article, the number of LightScribe-enabled DVD burners has dropped by 30% in the second quarter of 2007.
Support for Hewlett-Packard's (HP's) self-developed direct disc labeling technology, LightScribe, appears to be on the decline as the percentage of LightScribe-enabled DVD burners to all DVD burners has dropped from 80-90% in the first quarter of 2007 to 50-60% in the second, according to sources from both Taiwan's optical disc and optical disc drive (ODD) making industries.

HP won support of LightScribe from global leading ODD brands and OEM makers, including Sony, Pioneer, Asustek Computer, Hitachi-LG Data Storage (HLDS), Toshiba-Samsung Storage Technology (TSST), and Lite-On IT, the sources pointed out. In mid-2006, HP's promotion of LightScribe culminated in more than 70 licensees, the sources indicated. A licensee of LightScribe has to pay initial lump-sum royalty fee of US$250,000-300,000, the sources noted.
The article also mentions that the declining support is most likely due to extra cost associated with the technology as well as the continued drops in OEM drive prices. If you'd like to read more, head on over to DigiTimes. Add a comment

InfoWorld has reported that Managed Copy may actually be implemented this year. One of the main features of AACS, Managed Copy would let you make a backup of a Blu-ray and HD DVD movie or transfer it to a portable device or home media server.
Under a licensing agreement in its final stages, consumers may get the right to make several legal copies of HD DVD and Blu-ray Disc movies they've purchased, a concession by the movie industry that may quell criticism that DRM (digital rights management) technologies are too restrictive.

The agreement, if supported by movie studios and film companies, could allow a consumer to make a backup copy in case their original disc is damaged and another copy for their home media server, said Michael Ayers, a representative of an industry group that licenses the AACS (Advanced Access Content System) copy-prevention system.
Ars Technica has reported that Managed Copy will not be implemented until AACS has been finalized. However, a few studios are expecting it to be in place by the 2007 holiday season. Of course, the way things are going, AACS could be cracked wide open by then. Add a comment

According to report by Tech-On, Sony recently presented their results on four-layer Micro-Reflector recording at this year's ODS meeting. A type of holographic recording, Micro-Reflector irradiates a disc on both sides, creating a set of virtual layers. Sony claims that this method is affected less by heat and is cheaper implement due to the use of existing blue-violet laser diodes.
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.

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.
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
