Abstract
Higher recording density demands constant flying height over the entire recording area of the disk, however, in the recording procedure, the head doesn't always keep constant flying height, the flying height variation influences the recording density. This paper studies the head-disk coupling in waveguide probe near-field recording, and derives the relationship curve between half amplitude wide of static light distribution as well as static recording density and near-field coupling gap by computer simulation. After defining statistical recording density, we discuss the relationship between flying height variation of the flying optical head and statistical recording density in near-field optical recording.
