<p>A convenient means for carrying personal information is provided by integrating an optical data carrier (17, 47, 48, 83) with normal, everyday, personally carried (61) or worn articles (11, 41). The optical data carrier (17, 47, 83) has a recording surface which may be either disk (91) or drum-shaped (83). The data carrier is demountably attached to such articles as wrist watches (Figs. 1-3), pendants, bracelets, earrings, belt buckles (Figs. 4-6), pens, and pencils (Figs. 7-8). In the case of disk-shaped data carriers, screw threads (31, 57, 95) may be used to demountably attach the data carriers to personally carried or worn articles. When demounted from the article the optical data carrier may be inserted into a reader/writer device. In this way the information stored on the data carrier may be read, appended to or changed. The storage capacity of such devices is in the several megabyte range. Thus, large amounts of information may be conveniently and safely stored in this manner.</p> |
