摘要： A system and method for directly measuring the alignment error in a fiber-optic coupler is disclosed. In one embodiment, an optical switch utilizes a beam deflection mirror. When the beam deflection mirror directs an incident light beam to a particular fiber, the incident light beam may enter the fiber at a location offset from the center of the fiber. When the incident beam is reflected at the opposite end of the fiber, the beam returns and exits the fiber exactly at the center of the fiber. The difference between the entry and exit points results in a return beam path different than the incident beam path. This different return beam path may be used to impinge upon a quadrant detector, whose anode currents may then contain a direct measurement of the distance between the entry and exit points on the fiber.

摘要： Fabrication of an MO disc, the formation of a master pattern of servo and track information, and the subsequent transfer of that pattern to a series of pits and grooves on a substrate. On top of that substrate, at least one sacrificial layer is provided atop a relatively hard layer. The recording stack may be provided with both silicon nitride and silicon dioxide top layers, with the silicon dioxide layer acting as a sacrificial layer to ensure that the hard layer, of silicon nitride, remains at the end of the process. A layer of aluminum or aluminum alloy may be deposited, with the aluminum plugs filling the grooves and pits (created by the embossed servo information) to a level higher than any of the adjacent layers of silicon dioxide, silicon nitride, or similar dielectric layer. Since the polishing rate of aluminum can be far faster than that of the silicon dioxide, then the aluminum can be etched or otherwise removed down to a level equal to or slightly below a planar surface with the silicon dioxide, with the silicon dioxide layer allowing for some small level of over polishing. The silicon nitride layer is protected completely; the silicon dioxide layer partially remains and is partially removed; and the aluminum metal which fills the grooves and pits would rise only to a level substantially equal the very flat top surface of the silicon dioxide.
摘要翻译：制造MO盘，形成伺服和跟踪信息的主模式，以及随后将该图案转移到衬底上的一系列凹坑和凹槽。在该基板的顶部，在相对硬的层之上提供至少一个牺牲层。记录堆叠可以设置有氮化硅和二氧化硅顶层，其中二氧化硅层用作牺牲层，以确保氮化硅的硬层保持在工艺结束。可以沉积一层铝或铝合金，其中铝塞将填充凹槽和凹坑（由压花伺服信息产生）提升到高于任何相邻二氧化硅，氮化硅或类似介电层的层。由于铝的抛光速度可以比二氧化硅的抛光速度快得多，所以可以利用二氧化硅蚀刻或以其它方式将铝去除到等于或略低于平面的水平，其中二氧化硅层允许一些小水平的抛光。氮化硅层被完全保护; 二氧化硅层部分残留并被部分去除; 并且填充凹槽和凹坑的铝金属将仅升高到基本上等于二氧化硅的非常平坦的顶表面的水平。

摘要： Marks with curved edges are used in data patterns and sensed with proximity recording. Circular, elliptical, and oval marks are examples of marks with curved edges that can be used in the present invention. The marks with curved edges are used to define data patterns (e.g. position error signal patterns) as a function of radius. If the marks with curved edges have been recorded longitudinally, an amplitude of a read back signal, such as a peak amplitude, is determined in order to generate a position error signal. If the marks with curved edges have been recorded vertically, an area under the curve of the read back signal is determined in order to generate a position error signal.

摘要： A method for self-servo writing begins by calibrating at least one ruler formed on at least one storage disk. A ruler is a position-sensing pattern that defines the radial position of a recording head. The calibration process determines at least one correction factor for the at least one ruler on the disk. A servo system is then activated and the correction factors are used when writing the final servo pattern. During the process of writing the final servo patterns, the correction factors are modified to account for variations in any repeatable disturbances and for errors caused by any non-repeatable disturbances.

摘要： A system and method for encoding read-only information comprises a storage medium, a plurality of position marks disposed on the storage medium, and a light beam directed towards the position marks to produce a reflection of the light beam from the position marks. The position marks are configured such that the reflection of the light beam is not responsive to a plane of polarization of the light beam. In one embodiment, the position marks comprise rows of substantially circular pits. The dimensions of the substantially circular pits depend on a wavelength of the light beam and a numerical aperture of a lens that directs the light beam towards the position marks.
