Abstract
The drag torque of a hard disk drive (HDD) is a key variable to its spindle motor. It should be accurately tested during R&D and mass productions of HDDs. This paper reviews its existing measurement methods currently used by HDD industry first. Then an effective method to measure the drag torque is introduced. Through the proposed method, the drag torque can be measured more precisely and easily
