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, and a memory card on which a moving picture, a still picture and sound data are written in combination. To still picture data fetched by a CCD, an identification code representing that the data is still picture data is added by a DSP, and resulting data is compressed in accordance with the JPEG system by a data compression circuit and written into a memory card. To moving picture data fetched by the memory card, an identification code representing that the data is moving picture data is added by a DSP, and resulting data is compressed in accordance with the MPEG system by a data compression circuit and written into the memory card. To sound data, an identification code representing that the data is sound data is added by a DSP, and resulting data is compressed in accordance with the WAVE system by a data compression circuit and written into the memory card.
