International ClassG11B 013/00Foreign Application Priority Data1992-09-28 JPAbstractA long time optical recording and repeated reproduction of multimedia information is possible. Using a printer system or printing process system, on a recording medium such as a sheet, the so-called multimedia information in the form of dot codes (36) together with images (32) and characters (34) is recorded. The multimedia information includes audio information such as voices, image information obtainable from a camera and others, and digitally coded data obtainable from a personal computer and other. A pen-like information reproducing device (40) is manually moved to scan the dot codes (36) and to take in the dot codes. The original sound is generated by a voice output device (42) such as an earphone, the original image information is outputted on a display such as a CRT, and the digitally coded original data to a page printer or the like.Other References
