    Abstract: An optical device comprises a substrate having a plane surface. An optical path is disposed on the substrate and extends in a plane parallel to the surface of the substrate. A recess intercepts the optical path. An optical element is provided for modifying light incident thereon. The optical element is moveable within the recess between a first position in which the optical element is located in the path and a second position in which optical element is remote from the path. A cantilever suspends the optical element for movement within the recess between the second and first positions in a direction normal to the surface of the substrate.

    Abstract: Un método para escribir datos y/o leer datos desde lugares de una superficie de medio de almacenamiento a través de una punta, comprendiendo el método: mover la punta (40) entre los lugares de la superficie; y, en cada lugar, aplicar selectivamente energía a la superficie a través de la punta (40) activando un elemento de calentamiento (30) para calentamiento y/o para relectura térmica en un modo por impulsos en que un sensor en voladizo (10) comprende el elemento de calentamiento (30) y la punta (40); y caracterizado por impulsar conjuntamente de manera selectiva a la punta (40) mediante la superficie en un modo por impulsos y en sincronización con la aplicación selectiva de energía.

    Abstract: Described is a method for erasing data recorded in a data storage device in which a data bit is written onto a surface by applying a first combination of energy and force to the surface via a tip to form a pit in the surface representative of the data bit by local deformation of the surface. The method comprises applying a second combination of energy and force via the tip to prerecorded deformations of the surface to be erased to substantially level the surface.
