Masanobu Yamamoto，senior managing director at optical disc development division of Sony，said the firms were able to use paper in the new disc as the Bluray technology does not require laser light to travel through the substratesubstrate.
The technical details of how it is possible to use paper as a data storagestoragen disc would be disclosed at a conference in Monterey，California，according to the statement.
The combination of paper material and printing technology is also expected to lead to a reduction in cost per disc and will expand usage，the two partners said.It has yet to be undecided when the disc will be commercially available.
The use of paper in electronics products is not new for Sony.
In 1950when Japan was still struggling to rise from the ashes of World War II，Sony，then called Tokyo Tsushin Kogyo，made magnetic tapes using a similar grade of paper to that used for ordinary envelopes.
Sony used racoon hair brushes to daubdaub magnetic powder over the paper to produce what it cally “SONI TAPE”，starting its history as an audiovideo products maker.
The Bluray disc format allows highcapacity opticaldisc storage to be used for such technologies as highdefinition televisions.
A group of manufacturers was set up in 2002to promote a common standard for the disc formatformat Dell Inc.，HewlettPackard，Hitachi，LG Electronics，Matsushita Electronics Industrial，Mitsubishi Electric Corp，Pioneer Corp，Royal Philips Electronics，Samsung Electronics，Sharp Corp，Sony Corp （NYSE：SNE—news—web sites）and Thomson.
索尼研发纸制DVD光盘
电子业巨头索尼和日本Toppan印刷公司联合研发了一种“纸制DVD光盘”，可以录制长达两个多小时的高清晰度图像，并可以用剪子轻易销毁，因而更能保证数据的安全。纸制光盘以蓝光技术为基础，容量达25GB，其51%的材质为纸张。
Toppan印刷公司的常务董事Hideaki Kawai在与索尼的联合声明中说：“纸制光盘用剪子就可以方便地销毁，因此在销毁光盘时能够保护数据的安全性。”
索尼光盘研发部门的高级常务董事Masanobu Yamamoto称，能够将纸作为新光盘的材料是因为，蓝光技术不要求激光穿透光盘片的基板。公司在加州蒙特里市举行的会议上透露了将纸用作数据存储光盘材料的技术细节。
两家公司还表示，将纸和印刷技术相结合还能够降低光盘成本，并使其用途更加广泛。不过这种新型光盘何时得到商业推广还有待确定。将纸用在电子产品中对于索尼并不是第一次。早在1950年，当日本在二战的废墟中重新创业时，当时称作Tsushin Kogyo的索尼就曾用纸制作磁带，纸张质地类似普通的信封纸。索尼使用浣熊毛做成的刷子将磁粉涂抹在纸上，生产出称作“索尼带”的东西，开始了其作为音像产品制造商的历史。
在蓝光磁盘格式下，高容量光盘存储技术还可以用于高清晰电视等领域。2002年，一些厂家设立了针对磁盘格式的共同标准，这些厂家包括戴尔、惠普、日立、LG 电子、松下电器、三菱电器、先锋、飞利浦电子、三星、夏普、索尼和法国的汤姆逊。
Blogging Extend to French Serious Field
When Vichy Laboratories，a unit of Paris cosmeticscosmetic giant L’Oréal，launched a blog to promote a new antiwrinkle treatment，it encountered a wrinklewrinkle it hadn’t anticipated.The Frenchlanguage blog featured a fictitious character named Claire who posted progress reports about her skin.Quel faux pasfaux pas .The site was quickly flooded with postingsposting from suspicious bloggers demanding to know why，if the product was so effective，Vichy didn’t invite real women to test it.Chastened company officials retooled the site and recruited several bloggers as testers.“My skin is definitely smoother...although it’s not so radiantradiant that you need to wear sunglasses to look at it，”reads one recent posting.
Welcome to France，where blogging is taken très sérieusement.An estimated 3million French people，or 4.9%of the population，have their own blogs，a higher proportion than any other major European country.While the U.S.has more than 9million bloggers，they make up just 3%of Americans.Although blogging is by and large a youth phenomenon，it has already caught the attention of the political and business establishment.And in some cases it’s setting off more fireworksfireworks than a Bastille Day celebration.
A 36yearold civiccivic activist and blogger named Christophe Grébert was summoned to a Paris courtroom to face charges of defaming the municipal government in the suburb of Puteaux.
His offense：Posting excerpts of a newspaper article that alleged a municipal employee had been fired for whistleblowing.（The newspaper also has been charged with defamation.）Grébert’s preliminary hearing was postponed until early 2006，but his case made national headlines.
In a sense，the Gallic embrace of blogging is no surprise.France has a long tradition of public protest，from the 1789revolution to the barricadesbarricade of 1968to the frequent strikes that snarl public services.“French people love to tell everyone exactly what’s on their mindsfar more than Germans，for example，”says Le Meur founder of Ublog.com，a French blog software and services company acquired by an American competitor，Six Apart.Le Meur’s personal blog，written in English and French，has attracted a large global audience with its wideranging coverage of blogging and other technology trends.
The single biggest promoter of French blogging is Skyrock，a radio station in Paris that launched a free bloghosting service at the end of 2002.Skyrock now hosts more than 2.3million blogs，mostly by listeners in their teens and early 20s.Skyrock President Pierre Bellanger says the blogging venture has boosted listenership while bringing in S｜6million a year in new advertising revenuerevenue from companies such as AdidasSalomon （ADDDY）and Apple Computer Inc.（AAPL），who pay for the right to post messages on personal blogs hosted by Skyrock.“It’s a gold mine，”he says.
While there’s not much political debate to be found on Skyrock blogs，blogging clearly played a role in France’s vote against the European Constitution.An anticonstitution site run by Marseille schoolteacher Etienne Chouard drew 700，000plus hits.“During this campaign there was a loss of credibilitycredibility n.可信性in the traditional media，and more and more people turned toward alternativealternative sources，”says Nicolas Vanbremeersch，who runs a blog featuring commentary on both sides of the issue.
