• In this paper, we measured frequency response functions of 1.8-in hard disk drives (HDD) from 5 to 70 degrees Celsius. After extensive studies, we find that several critical steps must be taken to secure good experimental results. First, the fixture must be designed to reduce thermal stresses. It can be done via a better clamping design of the fixture or a reduction of mismatch of coefficient of thermal expansion between the fixture and the HDD. Second, environmental noise may come from traffic noise or from fixture connectivity, which range from 20-200 Hz and 1-20 Hz, respectively. Isolation of the environmental noise will significantly improve the experimental measurements from 1-200 Hz.
