Optical storage systems based on air-bearing-suspended optical heads in a near-field configuration. Such a system comprises an optical head for reading and writing data and a head positioning system, an optics module including beam relay optics and signal detectors, and a medium holding and loading module to hold an optical medium. An electronic control system is also provided to control the system operation. The optical head includes a near-field lens with a high index of refraction and in a near-field configuration in which the near-field lens has a numerical aperture greater than unity when the spacing between an exit facet of the optical head and a recording layer in the optical medium is a fraction of one wavelength of optical beam.

A deflection mirror tower (DMT) of a multiple-disk array, optical storage system includes a plurality of prism members, each having an angular mirror surface, arranged along a vertical axis of the DMT and configured at a predetermined angular orientation to deflect a laser beam to a respective disk surface. The DMT is generally fabricated using a two-level partitioning process. Several prepared glass substrates, i.e., one for each mirror type, are initially sliced into bars having predetermined geometries. A bar from each substrate is sequentially aligned to a master reference and bonded to adjacent bars to form an intermediate bar stack. The stack is then segmented into a plurality of DMT components, each having a plurality of prism members.

An apparatus is used with an optical disk drive for directing a beam of light to a surface of an optical disk. The apparatus has a beam shifter configured to direct the beam from a first path (along which the beam is generated) to a second path which is substantially parallel to the first path. An imaging lens is configured to direct the beam from the second path along a third path which passes near the front focal point of an objective lens (located near the surface of the disk). The third path and the first path diverge at an angle based on the distance separating the first and second paths.

摘要:
A lens/mirror tower (LMT) of a multiple-disk array, optical storage system includes a plurality of lens and mirror elements integrally formed on a monolithic, optically-clear substrate. There is a specific lens/mirror set for each recording disk surface of the optical storage device; however, the mirror elements are preferably configured as one reflective surface of the substrate. The lenses are molded onto the opposite surface in a single operation that fixes their relative positions. The LMT is generally fabricated using a lens replication process. Initially, a glass substrate is formed with a trapezoidal configuration. A lens array mold is also formed with a plurality of cavities arranged in overlapping pairs. The cavities are filled with optical-quality resin and the mold is applied to the surface of the substrate opposing the reflective angular, e.g., 45.degree., surface. Once cured, the resin serves as an array of lenses that are aligned with the optical paths to the objective lenses of the disk array.
摘要:
A remote fine positioning mechanism of an optical storage device includes a stationary galvanometer-controlled mirror (galvo mirror) and an imaging lens, the imaging lens positioned to provide an image of the galvo mirror at the front focal point of an objective lens mounted to an optical head assembly. The galvo mirror functions as a beam steering element that is rotated about a steering axis to change the angle of incidence of a collimated laser beam with respect to the objective lens during track selection operations. Thus, for rotation of the galvo mirror to change the direction of the laser beam, the system operates as though the mirror were physically located at that focal point. To perform the imaging function, the imaging lens decollimates the beam. A collimation-correction lens is therefore provided to ensure, in combination with the imaging lens, that the laser beam remains collimated when it reaches the objective lens.
