Abstract
A high resolution scanner apparatus has a disc upon which is mounted an original to be scanned. The disc may include a track for providing high accuracy tracing of the original. If the original is transparent, such as a photographic film, the disc may include a transparent first disc upon which the original is mounted and a second disc upon which a spiral track is provided, the first and second discs being mounted coaxially to rotate together. The discs may be compact or laser discs. A slide structure has at least a first arm for reading the original. The slide structure may include a second arm for tracing the track when included. The second arm may also include a light source for illuminating the original through the transparent first disc. The slide structure moves radially with respect to the discs, either using a precision controller or according to the tracing of the track by the second arm. If the original is not transparent, such as a printed original or a photographic film on a white sheet, a single disc may be used with the original mounted on one side and the optional track being on the other side. Then the first arm provides a light source for illuminating the original for reading using reflected light. The track may store bit clock information to allow a control circuit to rotate the disc(s) at a constant linear velocity.
