摘　　要：为进一步提高硬盘的转速设计了磁悬浮硬盘。针对磁悬浮硬盘的结构特点 ,提出了基于力控制的混合式磁悬浮硬盘的概念 ,介绍了力控制混合式磁悬浮硬盘的基本工作原理。给出了一个基于力控制的混合式磁悬浮硬盘的设计方案 。The speed of the hard disk drive (HDD) plays a very important role in the computer performance. The HDD becomes a bottleneck in the further increase of working speed of a computer system. To increase the rotation speed of a spindle motor is a possible way to improve the working speed of HDD. This paper presents a new concept of a magnetic levitated HDD using a hybrid magnetic bearing based on force controlling. The principle of this magnetic levitated HDD is introduced and its structure is described. The design of structure parameters for the magnetic levitated HDD is also discussed.
