摘要： A disk cartridge has a rotary inner shell, or shutter, to permit access to a data-storage medium disposed within the shell. A driving-access opening is located in a bottom surface of the cartridge's outer shell to allow a drive mechanism to rotate the storage medium. A portion of the inner shell projects into the driving-access opening to aid in the rotational alignment of the shell. The outer shell has a wedge-shaped disk-access opening. The inner shell rotates over a predefined arc to expose the data storage medium via the disk-access opening. A liner is disposed between the inner and outer shells to reduce sliding friction between the shells.

摘要： A system and a method for determining the density in which fibers are disposed along a planar surface employs a source of irradiance and a detector of irradiance in optical communication. A planar surface is positioned slightly below the optical path between the source and the detector. The fibers disposed along the planar surface interrupt the transmission of irradiance between the source and the detector. This interruption causes a decrease in the quantity of irradiance reaching the detector, resulting in a corresponding drop in the detector's output voltage. The density in which fibers are disposed along the planar surface can be determined by comparing the detector's voltage output with a pre-established baseline relating voltage output to fiber density.
