APERTURE STOP FOR A FLYING OPTICAL HEAD

摘要

An optical head (100) for performing optical data operations relative to a medium (118) includes a slider body (154) and at least one lens (150). Positioned between the slider body (154) and the lens (150) is an aperture stop (158) for blocking the transmittance of light. The aperture stop (158) includes an opaque layer that circumscribes a transparent region.
