Abstract
In the data center, which manages a huge amount of information, a hard disk drive which is inexpensive and has a large storage capacity is mainly used. However, since the number of HDD operations increases as information volume increases, it is now required to save HDD power. In response to this problem, development of an air bearing spindle to which an air bearing is applied is being carried out. However, there are no examples that have come into practical use due to low impact resistance and low productivity. In this resear ch, to reduce the dynamic characteristics of the HDD spindle motor, the purpose is to develop a small gas bearing spindle of a new structure. This paper report the processing conditions of bearing grooves by laser processing to obtain the groove processing characteristics required for robust optimum design of bearings.
