Method and apparatus to determine fly height of a recording head |
摘要 |
The invention features a fly height measurement system for measuring fly height of a slider over a storage disc. The fly height measuring system includes a source of light, a slider, a detector module and a processor. The source of light produces light along a light path. The slider includes an objective lens positioned such that light from said source hits the objective lens and is directed toward a surface of a disc. Light propagating from the disc is directed to a detector. The processor estimates the fly height of the slider based on detector module output.
