International ClassG11B 007/09AbstractA micro-objective lens is carried on an air bearing slider with an optical passage through which the lens focuses an energy beam onto a spot on an optical data storage medium. The slider accomplishes automatic focusing. An RF coil is affixed to the slider facing the storage medium and surrounding the beam axis. The proximity of the coil lowers power switching requirements.Field of SearchSolid state optical element with plural dissimilar optical components (e.g., using I.C. block, etc.)Elastic, flexible, pliant or spring support of lens or mirror Flat flexible support (e.g., parallel leaf spring, etc.) While track jumping or crossing With detail, configuration, or adjunct of element having slit or aperture in radiation path Lens movable in its plane Lens mounts | |
