ABSTRACT:
A data recording method error-correction-code (ECC)-encodes and modulates data of a file to be recorded in units of data blocks, and records the encoded and modulated data on a digital versatile disk-random access memory (DVD-RAM). Dummy data is added to make a last data block when the size of a file to be recorded is not an integer multiple of a data block, and then the last data block is ECC-encoded and modulated for recording the same on a DVD-RAM. The recording of data is performed in a recording region of a DVD-RAM where no data is recorded, and also starts from a recording region just next to the last data even when the last data of the previously recorded file includes dummy data.
