A novel optical head slider for near-field recording is proposed. A air bearing pad pattern formed on the apex of cantilever-like polymeric waveguide, and using the cantilever itself as a suspension of slider, function of flying slider, suspension, and waveguide are all included into one body structure. This structure (flexible head slider) can be fabricated by the method similar to lithographical technique. This structure will be expected to have great advantages in miniaturization of head assembly, simplification of assembling and optical trimming process, and more, lightweight of head assembly brings wider tracking bandwidth. In this paper, we report static floating characteristics of flexible head slider. Velocity dependency of flying attitude and adaptability against z-height offset was examined.
