Abstract: A recordable and/or rewriteable recording medium for storing still picture data, and recording and/or reproducing method and apparatus therefor. The recording medium stores still picture group information for grouping a plurality of still pictures in order to manage the still picture at a group level, and stores audio group information for grouping additional audio data added to the still picture data after the still picture data are recorded. Therefore, large-capacity still picture data and additional audio data added thereto can be recorded using a minimum amount of management information. Further, during reproduction, data can be displayed and edited in units of the respective still pictures. Also, it is possible to cope with after-recording of the audio data.

In addition, the method is an environmentally friendly process entailing reduced waste treatment cost when compared to conventional mesitylene production methods. Therefore, high value-added mesitylene can be separated from low value-added C9+ aromatic compounds at lower cost compared to conventional methods.
