ABSTRACT:
A data recording apparatus which simultaneously records data to a plurality of radially divided recording areas of a disc recording medium by the CAV method, including a data dividing unit for dividing the input data into amounts of data proportional to the radial lengths of the plurality of recording areas and a plurality of data recording units for simultaneously recording the data to the corresponding recording areas at data recording rates proportional to the radial lengths of the recording areas; a data reproducing apparatus which reproduces data recorded by such a data recording apparatus including a plurality of data reproducing units, provided corresponding to the data recording areas, for simultaneously reproducing data from the recording areas, and a data rearranging unit for rearranging the data reproduced from the recording areas to the same order as the original input data; and a data recording/reproducing apparatus including such a data recording apparatus and data reproducing apparatus.
