Chinese doctoral student at the University of Sydney the magic found hard drive-hard drive capacity expanded a hundredfold, storage-IT information
14th at Sydney University announced that Chinese students in the school study Dr Chen Zibin with collaborators at the University of Wollongong's newest finding: by electron beam "radiation" on special ceramic materials can expand the memory of your computer's hard disk capacity 100 times. This study responds to consumer demand for increased hard drive memory capacity of the computer, but also in future is expected to reduce the current in the world, estimated at more than 2.5 billion hard drives.
The materials science research results were recently published in the United States Physics journal physical review letters.
The study's lead author, Chen Zibin was the University of Sydney engineering and PhD, Division of information technology, and he graduated from South China University of technology, and received Australia fellowships and Australia ceramic society fellowships and other awards.
Chen Zibin said: "all hard drives connected to the end of the world to line up, they would circle the Earth 5 times. Making the hard drives using aluminium and other non-biodegradable materials. ”
According to Chen Zibin introduced, an important challenge in this area is to find a way to improve memory capacity without increasing hard drive size. This project focuses on memory storage of materials science. In some of oxide ceramic called ferroelectric materials, to switch small electric dipole field. Two opposite direction of dipole can be used for computer memory two logical signal "0" and "1".
He believes that the key challenge is how to put a domain in the "0" and "1" to toggle between. Traditional techniques using local heating, mechanical stress or bias-these all have some drawbacks. "We found that the electric field of a high energy electron beam into this work and has the ability to reduce the size of the current domain to the 1%, so that data storage capacity increases 100 times. "Chen Zibin said.
Chen Zibin said the study outlines a scientific blueprint to create the next generation a better, greener and stability in your computer's memory.

悉尼大学中国博士生神奇发现：让硬盘容量扩大百倍 - 硬盘,存储 - IT资讯
悉尼大学14日对外宣布，在该校研读博士的中国留学生陈子斌与伍伦贡大学的合作者最新发现：通过把电子束“照射”到特种陶瓷材料上可以扩大计算机硬盘的内存容量100倍。这项研究回应了消费者对增加计算机硬盘内存容量的需求，同时也有望在未来减少目前在世界范围内使用的估计超过25亿个的硬盘驱动器。
这项材料科学研究成果近日发表在了美国物理学会的《物理评论快报》期刊上。
该研究的主要作者陈子斌是悉尼大学工程与信息技术学部博士研究生，他本科毕业于华南理工大学，并获得了澳大利亚研究生奖学金和澳大利亚陶瓷学会研究生奖学金等奖项。
陈子斌说：“把世界上所有的硬盘驱动器首尾相连地排列起来，它们可以绕地球5圈。制造这些硬盘驱动器使用了非生物降解的铝和其他金属材料。”
据陈子斌介绍，该领域的一项重要挑战就是找到一种方法，在不增加硬盘尺寸的前提下提升内存容量。这个项目的重点在记忆存储的材料科学。在某些被称为铁电材料的氧化物陶瓷中，存在可切换电偶极子的微小域。两个相反的偶极方向可以被用作计算机内存的两个逻辑信号“0”和“1”。
他认为挑战的关键是如何把域在“0”和“1”之间进行切换。传统的技术采用局部加热、机械应力或者电偏压——这些都具有某些缺陷。“我们发现高能量电子束引入的电场可以实现这项工作并且有能力缩减当前域的尺寸到它的百分之一，从而让数据存储能力增大100倍。”陈子斌说。
陈子斌说这项研究勾勒了一副科学蓝图来制造下一代更好、更绿色环保和稳定的计算机内存。
工程与信息技术学部的廖晓舟教授和西蒙·林格教授共同指导了这项博士研究，他们的工作是学部材料与结构研究组的一部分。
