Spherical aberration correction using flying lens and method |
摘要 |
An optical access device for a moving optical data storage media having a flying lens near an outer surface of the media, and an objective lens spaced from the flying lens, with the flying lens and objective lens co-operating to substantially offset a variable range of negative spherical aberration occurring in the media by forming a positive spherical aberration which substantially cancels the negative spherical aberration.
