| Summary: | Including: 3 parts. With greater demands for increasing data storage capacity, the flying height of the slider head has decreased to less than 50 nanometers, for example, to reach a storage density of 1 Tbig/in2 , a flying height of 3 nanometer is necessary [Wu & Bogy, 2001]. At this flying height, the topography of the surface of the disk and the slider head has to be taken into consideration. The extremely thin air-bearing beneath the slider head provides the necessary lifting force. However, at start-up and working conditions, contact is highly possible and two tribological problems arise: friction and wear. To protect the head and disk surface from these problems, a thin film lubricant is applied to the disk surface. |
