PURPOSE: A holographic digital data storage device and a data inputting and outputting method of the device are provided to minimize influences of noise of the corner of a page when data are reproduced. CONSTITUTION: A holographic digital data storage device includes an input data converter(100), an encoder(110), a decoder(130), and an output data converter(140). The input data converter converts the outer region of a page of rectangular page data inputted into a recording and reproduction unit, to generate converted page data. The encoder codes the converted page data to transmit the coded data to the recording and reproduction unit. The decoder decodes converted page data reproduced by the recording and reproduction unit. The output data converter inverse-converts a converted outer region of the page of the decoded page data, to generate rectangular page data.
