Flying Characteristics of a Slider for Grooved Discrete Track Media

Abstract

Both static and dynamic analyses of a slider flying over an embossed disk with discrete data tracks and servo marks are presented. It is shown that the averaged Reynolds equation may be employed to design a reliable slider-disk interface for a grooved discrete track disk. The mechanical resonance problem associated with a slider flying over a periodic pattern of em-bossed servo segments is analyzed and resolved. It was found that there is no critical change in flying height when using an embossed discrete track disk.
