Abstract

A data recording apparatus for a still camera has a microphone to which an external voice is input. A voice signal of the input external voice is converted into a bar-code pattern data by a pattern converter and then recorded onto a silver-salt film through LC-cell. A developed pattern data on a photograph is read out by a bar-code reader and decoded into the original voice signal. A voice corresponding to the decoded voice signal is generated through a speaker.
