GE MOVES FORWARD WITH HOLOGRAPHIC DISC STORAGE

通用推进全息光盘存储技术

GE Global Research recently announced they are forging ahead with a project that could greatly increase the capacity for storage-on-disc technologies. Their plan is to distribute discs with 500 GB of holographic optical storage.

通用公司全球研发中心近期宣布,研发人员目前正着手推进一个项目,该项目可以大大提高光盘的存储容量。在这一项目中,他们计划为全息光盘开辟500GB的存储空间。

Current optical storage technologies like Blu-ray and DVD discs are only capable of storing information in the surface of the disc. By using holograms’ three-dimensional patterns, information can be written and stored at controlled debts that utilize the disc’s entire volume of storage space.

当前的光存储技术,比如蓝光光盘和DVD光盘,只能将信息存储于碟片表面。而通过应用三维全息图像,则可在控制项目经费的前提下,利用光盘的全部存储空间来存、写信息。

Think of these discs as being file cabinet holograms — really big ones.

想像一下,这些可以充当文件柜的全息光盘——那容量可是相当大啊!

Because they can make use of the material’s entire storage space, GE says these micro-holographic discs have the storage capacity of 20 single-layer Blu-ray discs, 100 DVDs or the hard drive of most laptops.

通用称,由于可以利用材料的全部存储空间,因此这些微型全息光盘的容量相当于单层蓝光光盘的20倍,DVD的100倍,而且能跟大多数“本本”的硬盘容量平分秋色。

“During the past two years, our research team has been focused on material improvements to increase the recording speed and making other key advances needed to ready GE’s micro-holographic technology for market,” said manager of the Applied Optics Lab at Global Research, Peter Lorraine, in a GE press release. “With a speed to match Blu-ray’s, discs made from GE’s advanced micro-holographic materials are an attractive solution for both archival and consumer entertainment systems.”

“过 去两年间,我们的研究小组一直致力于改进材料,以提高存储速度;同时改良其他的关键技术,为微全息技术的市场应用做准备。”通用全球研发中心应用光学实验 室主任Peter Lorraine在新闻公告中说道,“由于存储速度与蓝光光盘不分伯仲,因此这些由改进版微全息材料制作的光盘,无论用作文档存储还是家庭娱乐,都不失为 一种十分诱人的解决方案。”

Eventually, GE says they want to create micro-holographic discs that can store more than one terabyte, or 1,000 gigabytes of data.

最后,通用称其还将研发容量为1TB(1000GB)以上的微全息光盘。

Not everyone is so gung-ho. John Webster, a senior partner at market research firm the Evaluator Group recently told Computer World he was concerned about the price-performance ratio of optical storage technology.

然而,并不是每个人都那么热衷。比如,Evaluator Group市场调研公司的资深合伙人John Webster,近期就对Computer World称,他对光存储技术的性价比有些担心。

“So they’re going to try this again?” he said. “It wasn’t the media, but all the machinery you need to make it work. At a price-per-gigabyte or -terabyte level, it just didn’t make sense.”

“所以他们还要再试一遍?”他说,“存储设备中,你需要它起作用的并不是存储媒介,而是机器整体!至于是按GB还是按TB计价,那并没有什么意义。”

Back in 2007, InPhase Technologies developed the industry’s first 300GB holographic optical disc, called the HDS-300R, and planned to sell them for $100 – $125 each.

早在2007年,InPhase科技就已研制出行业第一款300GB全息光盘,命名为HDS-300R,并打算以每片100~125美元的价格出售。
