IBM科学家在《科学》杂志上报道说, 他们找到了一种使计算机数据存盘容量扩大30倍的方法。这一新技术利用5年前科学家发现的“巨磁阻”现象,它是指某些可以制作计算机数据存盘的材料被置于磁场环境中之后,其电磁阻力会发生变化。IBM预计,新技术得到运用后,本世纪末数据存盘上每方英寸的信息存储密度可增到100 IBM scientists report in Science that they have found a way to expand their computer data storage capacity by a factor of 30. The new technology takes advantage of the “Giant Magneto Resistance” phenomenon discovered by scientists five years ago. It refers to the change in electromagnetic resistance of materials that can be used to create computer data after being placed in a magnetic environment. IBM estimates that as new technologies become available, the information storage density per square inch of data saved at the end of the century will increase to 100
