  • Publication number: 20020038944
    Abstract: 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 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.

  • Patent number: 6228482
    Abstract: 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.
