Patent EP-0435495-A2 (EP)
Inventor: LEMKE JAMES U
IPC: G11B23/50
Filed: 1990-12-07
Abstract: An information storage apparatus is disclosed for reading and/or writing information on a rigid disk (10) which includes a non-Newtonian liquid bearing interface (70) between a transducer (21) and a storage medium (10), instead of a conventional air of Newtonian liquid bearing. The non-Newtonian liquid has a composition which exhibits plastic or pseudoplastic flow at high rates of shear. Preferably, the liquid is of the class of compounds whose viscosity shows a negative dependence on shear rate. Thus, as the relative speed of the transducer and the storage medium increases, while their relative spacing decreases, the increasing shear rate to which the liquid bearing is subjected causes the viscosity of the liquid to reduce. Resultantly, very low flying heights can be achieved, which increases the potential storage density on the storage medium, while the reduced drag exerted on the transducer by the lowered viscosity greatly reduces the power required to rotate the medium.

Abstract: This invention discloses a semiconductor laser incorporating a plurality of resonant optical waveguide array cells. In each of the resonant optical waveguide array cells, leaky waveguide elements are coupled together such that radiation leaked from one antiguide element is coupled with radiation propagating along another antiguide element across an interelement region. As the radiation propagates through the array it is deflected at each end of the array until it builds up enough optical gain to reach lasing threshold. Then, radiation is leaked from the sides of each array such that this radiation can impinge other resonant optical waveguide arrays and be coupled with these arrays in phase to develop a laser beam having a higher intensity which can be achieved with a single array semiconductor laser.
