A method and apparatus for recording andor reproducing data to andor from a holographic storage medium and a holographic storage medium therefor are provided. The elongated, rectilinear bone fusion device also provides bony in-growth within the bores along the exterior surface of the bone fusion device. The extension leg is comprises of a lateral member and a second member pivotably engaged thereto. The statistics indicate a frequency of enforcement for each of the plurality of filter rules. After executing the suggested tuning action, post-action database system performance is measured according to the second procedure. This method can obtain hybrid alignment of discotic liquid crystal via a simple process, and therefore reduce the complexity for manufacturing the negative optical compensation assembly.
