DATA PROCESSING APPARATUS, DATA RECORDING DEVICE, DATA REPRODUCING DEVICE, AND RECORDING MEDIUM HAVING PLURAL RECORDING LAYERS

摘要

PROBLEM TO BE SOLVED: To enable writing to a disk by correcting previously prepared image data as easily as possible in order to download and record contents to a plurality of layers of recording media of write once type or rewritable type. SOLUTION: The data processing apparatus generates data to be written continuously on first and second recording layers of a recording medium. The first and second recording layers have first and second storage capacities, respectively. The data processing apparatus includes: a data storage in which the data to be written is split into, and stored separately as, first and second data, the first data having a data size that is smaller than the first storage capacity, the second data having a data size that is smaller than the second storage capacity; a communication section for getting the end address of a data recordable area of the first recording layer; a controller for adjusting the data size of the first data such that the beginning of the first data is written at the start address of the data recordable area of the first recording layer and that the end of the first data is written at the end address gotten; and an output section for outputting the first data and the second data, the data sizes of which have been adjusted.
