还是看原文报导实在些. 资料来源: UK Independent http://tinyurl.com/hv6ug By Charles Arthur Technology Editor Published: 16 June 2001 Scientists Discover Fungus That Eats CDs COMPACT DISC users beware: Your prized music or data could be under attack. Scientists have discovered a fungus which, under the right conditions, will literally eat compact discs and render the information on them completely useless. Victor Cardenes, a geologist at a leading Spanish research institute, made the discovery on a trip to the Central American country of Belize, where some friends showed him a CD which had a strange discolouration that left it almost transparent, and unplayable. 技术编辑 查尔斯‧奥塞 2001年6月16日 科学家发现吃CD的霉菌 CD用家注意! 你所自豪的音乐CD和资料光碟,可能正遭受到攻击. 科学家发现某种 霉菌将逐渐吃掉你的CD,并让里头的资料完全读不到. 来自西班牙首要研究机构的地质学家,维克多‧卡登尼斯,在往中美国家贝里斯的 旅途中,被当地的朋友告知CD有怪异的变色,呈现透明且无法播放. 注:消息显示Victor Cardenes似乎是隶属於MNSN(Madrid's National Museum of Natural Sciences,马德里国家自然科学博物馆)的研究人员 Intrigued, he took it back to Madrid, where he put the sample under an electron microscope at the Superior Council for Scientific Research. There, he found that a fungus had burrowed into the disc from its outer edge, and eaten up the thin aluminium reflecting layer and the polycarbonate resin that comprises the CD. Information is stored on CDs by a pattern of "pits" in the aluminium layer, which is held in the resin matrix. That is then covered in a transparent lacquer. To read the disc, laser light is shone onto the aluminium; the presence or absence of a pit is then read as a digital 0 or 1. If the pits cannot be located, the CD is unreadable. 好奇心的驱使让卡登尼斯把CD带回马德里. 在高等科学研究会的电子显微镜下, 他发现霉菌从CD的外缘钻入,吃掉薄薄的铝反射层和组成CD的聚碳酸酯树酯. CD资料是以凹槽的形式记录在铝层,铝层再被包在树酯中,最後覆上透明漆. 读片 时雷射光射向铝层,此时槽的出现与否将决定资料是0或1. 若槽抓不到,CD就读不到. "If you look at the CD from the shiny side, in the places where the fungus has been you can see through to the other side," Dr Cardenes said. Biologists at the council concluded that the fungus belonged to a common genus called Geotrichum, but admitted they had never before seen this particular species. The cooler and drier weather in Madrid caused the fungus to stop growing - suggesting that it thrives on tropical heat and humidity. "当你把CD对向亮处,霉菌吃掉的部份会被光透过去." 卡登尼斯博士说. 生物学家 认定那是Geotrichum属的霉菌,但他们也坦承从未见过这样特殊的菌种. 马德里那较冷且乾燥的气候让霉菌安份不少,这或许可以推测出湿热的天气会让 它们活力旺盛. Hans Hofstraat, chief organic chemist at the electronics giant Philips - which invented the CD in 1973 - said the case is "probably a freak incident caused by extreme weather conditions" and insisted the fungus poses no threat to the billions of discs used around the world. 大飞利浦集团-CD就是在1973年被它发明出来-的首席有机化学家汉斯‧霍斯崔特说, 那应该只是在贝里斯极端气候条件下所造成的个案,他并断言霉菌不可能对世界其他 地区的数十亿张CD构成任何威胁. 注: 有传言说卡登尼斯原文是刊登在Nature,请点 http://www.nature.com/index.html 但我用他的名字一时间竟查不到,此点後叙. =========================================================================== 贝里斯? 请点 http://tinyurl.com/guv3k 总之看起来似乎真有这回事,但证据力不足,尤其Nature查不到相关资讯十分可疑. 经过仔细搜寻後,我发现另一篇非常有趣的文章. =========================================================================== 待续..... --
