硬盘驱动器巨磁电阻(GMR)磁头:从微米到纳米

近年来电脑硬盘存储密度的飞速增长(年增长100％)已超出摩尔定律的预言．这种惊人的高速增长中，最关键的因素是自旋阀纳米多层膜结构，即巨磁电阻(GMR)读传感器磁头的应用．事实上，巨磁电阻磁头读传感器(reader sensor)已经实现由微电子器件向纳米电子器件转化，并且形成大规模产业．这一过程包含了自旋电子学、材料科学、微电子工程学、化学、微机械力学和工程学等诸学科和相关微加工技术综合性挑战极限，进入纳米科技领域实质性进步．

Giant magnetic resistance head for hard disk drives:from micro to nano

Hard disc drive heads based on giant magnetic resistance and tunneling magnetic resistance integrate the latest developments of spintronics, material science, microelectronic engineering, chemistry, microair dynamics, micro\|mechanics and engineering. The technology has been continuously challenging the technical limitations of deep sub\|micro device manufacturing, and has achieved a breakthrough over the 100nm threshold in all the three dimensions, presenting the first successful example of the transition from micro-to nano-device in the mass production of hard disk drives.
