摘要： Disclosed is an optical data storage medium with enhanced contrast. The optical data storage medium includes a substrate having oppositely facing first and second surfaces. A first metal/alloy layer is formed overlaying the first surface of the substrate. The first metal/alloy layer is formed from tin, antimony and element selected from the group consisting of indium, germanium, aluminum, and zinc. After the first metal/alloy layer is formed, a first dielectric layer is formed overlaying the first metal/alloy layer. This dielectric layer is formed from silicon oxynitride. The first metal/alloy layer is positioned between the substrate and the first dielectric layer.

摘要： A user-removable optical data storage system is provided. A rotatable first-surface medium is enveloped in a cartridge. The cartridge provides relatively large data capacity such as about 0.25 Gbytes or more despite a relatively small size such as about 35 mm×35 mm×3 mm. Preferably the cartridge substantially seals the data surfaces of the medium when the cartridge is withdrawn from a drive and at least a portion of one surface is automatically exposed to the objective of an optics arm when said cartridge is inserted in the drive. Tracking involves rotating an optic arm about an axis parallel to the disk rotation axis. Focus can involve pivoting the arm about an axis parallel to the disk surface.

摘要： Systems and methods are provided or use with a light source which generates a light beam. These systems may include a detector which detects light beam information and which determines whether multiple modes are present in the light beam so that the light source may be adjusted. These systems may further include a beam splitting device, such as an optical wedge, to provide two sample beams that intersect to provide a fringe pattern. The detector may then detect this fringe pattern and compute a visibility value that may be used to determine whether multiple modes are present.

摘要： Disclosed is a method of attaching components of an optical head. In one embodiment, first and second optical assemblies of the optical head are positioned adjacent to each other. The first optical assembly may include a first optical element, and the second optical assembly may include a second optical element. Both of the first and second optical elements are configured to transmit light for reading or writing data to an optical data storage media. The position of a first optical assembly is adjusted with respect to the second optical assembly until the first optical element and second optical elements are in optical communication with each other. Thereafter, the first and second optical assemblies are rigidly connected while the first and second optical elements are in optical communication with each other.

摘要： Aspects of the present invention are generally directed to a holographic system. Generally, aspects of the present invention are directed to allocating power of a light beam generated by a coherent light source among the various discrete light beams used in a holographic system. Specifically, a variable optical divider is incorporated into an optical steering subsystem of the holographic memory system to redirect the coherent light beam into one or more discrete light beams, and to dynamically allocate power of the coherent light beam among the discrete light beams.

摘要： Micro lenses are fabricated using processes which operate on multiple lenses at a time. In one embodiment, wafer-scale processing includes employing photolithography for defining gray-scale masks which permit relatively smooth or continuous curvatures of lens surfaces to be formed by, e.g., reactive ion etching. Processes and materials are used which achieve desired etching at a sufficiently rapid rate such as etching to a depth of about 200 micrometers in less than about 10 hours. Wafer-scale molding processes can also be used. Diffractive features can be formed on or adjacent lens surfaces to provide functions such as dispersion correction. Also, sub-wavelength scale features may be etched to provide quarter-wave plate functionality, birefringence, anti-reflective functions and the like. Structures such as mounting rings and/or crash stops can be formed integrally with the lens body, eliminating the need to glue or otherwise couple separate components.
