摘要： An optical data storage system includes an optical disc and an armature adjacent the disc. An optical transducer mounted on the arm provides an optical beam output directed parallel to the plane of the disc. An optical actuator mounted on the arm and positioned in the optical beam adjusts the direction of the optical beam and a mirror is positioned to direct the optical beam in a direction perpendicular to the disc and toward the disc. An optical head is positioned at a distal end of the arm and is adapted to couple the optical beam to the optical disc. An arm actuator is coupled to the arm to move the arm relative to the disc and provide coarse positioning of the optical head relative to tracks on the disc. The optical actuator provides fine adjustment of the optical beam between tracks on the disc which are proximate the optical head due to the coarse adjustment by the arm actuator.

摘要： An optical data storage system that includes an optical source and an optical storage medium. The system includes a plurality of armatures positioned adjacent to the optical storage medium. Mounted on each armature are elements that perform functions such as beam-splitting, beam-shaping, relaying and fine tuning to collectively form an armature-mounted optical coupling system. An optical switch couples the optical source to each of the armature-mounted optical coupling systems. This configuration of an optical data storage system ensures that one optical source can be utilized for a plurality of optical detection systems.

摘要： When a dye material layer is spin-coated on an optical storage medium of the type having grooves fabricated in a substrate thereof, the dye material layer surface has depressions in the vicinity of the grooves. These depressions have a profile which is a function of the distance from the center of the storage medium. To compensate for the radial dependence of the depressions, the geometry of the grooves is changed by varying the base dimension of the groove as a function of the distance from the center of the storage medium. In this manner, the difference in phase for radiation traversing the storage medium by an optical path that includes a groove as compared to an optical path that does not include an associated groove is constant as a function of distance from the center of the storage medium. The phase difference which is a constant as a function of distance from the center of the storage medium is important in the generation of signals used in tracking the groove.
摘要翻译：当将染料材料层旋涂在具有在其基材中制造的槽的类型的光学存储介质上时，染料材料层表面在凹槽附近具有凹陷。这些凹陷具有与存储介质的中心的距离的函数的轮廓。为了补偿凹陷的径向依赖性，通过根据从存储介质的中心的距离改变凹槽的基部尺寸来改变凹槽的几何形状。以这种方式，与不包括关联凹槽的光路相比，通过包括凹槽的光路穿过存储介质的辐射的相位差是作为与存储介质的中心的距离的函数的常数。作为与存储介质的中心的距离的函数的常数的相位差在生成用于跟踪凹槽的信号中是重要的。

摘要： Arrangements are disclosed for generating a well defined traveling wave beam substantially unaffected by diffractive spreading. In different embodiments, the beam can be an electromagnetic wave, particle beam, a transverse beam, a longitudinal beam such as an acoustic beam, or any type of beam to which the Helmholtz generalized wave equation is applicable. Pursuant to the teachings herein, a beam is generated having a transverse dependence of a Bessel function, and a longitudinal dependence which is entirely in phaser form, which results in a beam having a substantial depth of field which is substantially unaffected by diffractive spreading. In first and second disclosed embodiments respectively, optical and acoustical beams are generated by placing a circular annular source of the beam in the focal plane of a focussing means, which results in the generation of a well defined beam thereby because the far field intensity pattern of an object is the Fourier transform thereof, and the Fourier transform of a Bessel function is a circular function. In a third disclosed embodiment, a microwave beam is generated by transmitting a coherent microwave beam sequentially through a phase modulator, having a periodic stop function pattern, and a spatial filter, whose transmittance is the modulus of the Bessel function, to generate a microwave beam having a transverse Bessel function profile.More specifically, several embodiments are disclosed of an integrated optical laser cavity and an integrated microwave maser cavity for increasing the efficiency of production of the laser or maser beam. The integrated laser and maser cavities are designed to generate directly from their own gain medium a Bessel-mode diffraction-free beam.
