Passive data recording onto magnetic layers of photographic film |
摘要 |
A magnetic recorder includes multiple permanent magnetic elements having magnetic orientations that impart a sequence of magnetic transitions to magnetic media of a photographic filmstrip contained within a camera. The permanent magnetic elements are external to the camera. The sequence of magnetic transitions comprise information that can be subsequently retrieved and provided to the photographic processor and/or photographer. The information can include identification of locale or other information of interest to the photographer. The magnetic recorder requires no power supply and is easily operated by a photographer virtually without regard to weather conditions.
