摘要： A magneto-optic recording medium having a reduced demagnetizing field threshold incorporates a thin recording layer having a thickness of less than or equal to approximately 15 nm, and preferably less than or equal to approximately 12 nm. The recording medium thereby exhibits a demagnetizing field threshold of less than or equal to approximately 150 Oe, and preferably less than or equal to approximately 120 Oe. Dielectric and reflective layers in the recording medium stack are tuned to achieve acceptable optical and magnetic characteristics for write and readout operations. The reduced demagnetizing field facilitates use of the recording medium in recording applications that use small magnetic fields for recording and erase. The recording medium is particularly useful in near-field, air-incident recording applications employing magnetic field modulation recording techniques.
摘要翻译：具有减小的去磁场阈值的磁光记录介质结合了厚度小于或等于约15nm，优选小于或等于约12nm的薄记录层。记录介质因此表现出小于或等于约150Oe，优选小于或等于约120Oe的去磁场阈值。调谐记录介质堆叠中的电介质层和反射层以实现用于写入和读出操作的可接受的光学和磁特性。减少的去磁场有助于在使用小磁场进行记录和擦除的记录应用中使用记录介质。记录介质在采用磁场调制记录技术的近场，空中记录应用中特别有用。

摘要： A rear suspension bicycle having a rear wheel with an axle, a frame including a seat tube and a down tube having a top and bottom ends, a pair of drop link members, one for either side of the rear wheel, each having a top attachment point and a bottom attachment point, and an axle attachment point for receiving the axle. A seat stay assembly including a front end and a rear end, and having a front pivotal attachment point adjacent the front end for attachment to the down tube defining a first pivot point, and a pair of rear pivot points, each for pivotal attachment to the top attachment point of one of said drop link members, forming together the second pivot point. A vertically flexible chain stay assembly, providing suspension spring force, having a front end and a rear end, and defining a front fixed attachment point at the front end, and a pair of rear pivot points at the rear end, the front attachment point being adjacent to the bottom end of the seat tube, and a pair of rear pivot points, each for pivotal attachment to the bottom attachment point of one of the drop link members, forming together the third pivot point. A damping member is mounted between the seat stay assembly and the frame. When the rear wheel is moved upwardly with respect to the frame, the chain stay assembly flexes upwardly, and the axle traces a complex curvilinear axle path generally upwardly, moving first rearwardly to a rearwardmost position, then forwardly along the upward axle path. The rear suspension transmits the pedal force generated by the rider efficiently into forward moving force without compressing, or otherwise activating, the suspension appreciably.

A seat stay assembly including a front end and a rear end, and having a front pivot point adjacent the front end for pivotal attachment to the down tube defining a first pivot point, and a pair of rear pivot points, each for pivotal attachment to the top attachment point of one of said drop link members, forming together the second pivot point. A chain stay assembly having a front end and a rear end, and defining a front pivot point at the front end, and a pair of rear pivot points at the rear end, the front pivot point for pivotal attachment adjacent to the bottom end of the seat tube forming the third pivot point, and a pair of rear pivot points, each for pivotal attachment to the bottom attachment point of one of the drop link members, forming together the fourth pivot point. A shock-absorbing element is mounted between the seat stay assembly and the frame. When the rear wheel is moved upwardly with respect to the frame, the axle traces a complex curvilinear axle path generally upwardly, moving first rearwardly to a rearwardmost position, then forwardly along the upward axle path. The rear suspension transmits the pedal force generated by the rider efficiently into forward moving force without compressing the suspension appreciably.
