The invention provides a picture data writing apparatus and method, a picture data reading apparatus and method, and a picture data writing and reading apparatus and method and by which a moving picture, a still picture and sound data can be written and read out in combination into and from a memory card (102), and a memory card (102) on which a moving picture, a still picture and sound data are written in combination. To still picture data fetched by a CCD (122), an identification code representing that the data is still picture data is added by a DSP (124), and resulting data is compressed in accordance with the JPEG system by a data compression circuit (125) and written into a memory card (102). To moving picture data fetched by a CCD (122), an identification code representing that the data is moving picture data is added by a DSP (122), and resulting data is compressed in accordance with the MPEG system by a data compression circuit (129) and written into the memory card (102). To sound data, an identification code representing that the data is sound data is added by a DSP (134), and resulting data is compressed in accordance with the WAVE system by a data compression circuit (135A,135B) and written into the memory card (102).
