Abstract
A data recording device that can easily and reliably manage a plurality of recording media or information recording surfaces even when a data compression rate largely varies with the contents of the data and that can record, for example, mass image data by effectively preventing the picture quality of an image represented by the image data from being degraded. The data recording device records image data after securing a region according to the preliminarily estimated number of recording media or information recording surfaces at the time of recording image data by using a coding method, by which a data compression rate largely varies with the contents of data. Thereafter, the data recording device records management date used for managing the plurality of recording media or information recording surfaces, on which the coded data is recorded, on the management region according to a result of recording.
