Development of Self Acting Air-Lubricated Ceramic Bearing for 1" HDD

1" HDD용 세라믹 공기 동압 베어링 개발

In recent years, the demand of mobile device, such as digital camera, camcorder and PDA, increases remarkably. So, requirements of the mobile information data storage used in the mobile devices increase noticeably also. 1" micro data storage is a kind of mobile storage. which has a CF type II form factor, and the similar structure of the general 3.5" HDD. In this paper, we developed the self acting air-lubricated ceramic bearing for the 1" micro data storage. The self acting air-lubricated ceramic bearing Is superior to the fluid bearing and the ball bearing on power consumption.
