设在加利福尼亚州圣何塞的IBM公司阿尔马登研究中心的研究人员已成功地在一平方英寸的磁盘上存储了多达十亿位的数据。这是迄今为止采用磁盘数据存储技术所获得的最高存储密度。这一成就有助于使磁盘技术在大容量信息存储的竞赛中赶上光盘技术。目前市场上出售的“硬”磁盘的数据存储密度约比IBM公司的这一新磁盘系统的存储密度低15到30倍。虽然IBM公司是在实验室中获得这一创纪律的成就的,但它指出“这个磁盘
Researchers at the IBM Almaden Research Center in San Jose, CA, have successfully stored as much as 1 billion bits of data on a one-square-inch disk. This is by far the highest storage density achieved with disk data storage technology. This accomplishment has helped make disk technology catch up with CD-ROM technology in a race to mass-store information. The data storage density of “hard” disks currently on the market is about 15 to 30 times lower than that of IBM’s new disk system. Although IBM acquired this disciplined achievement in the lab, it states that "this disk
