A recording apparatus which effects recording after performing padding an area between an end position of AV data and the end position of a sector, with NULL packet data having no image information, no speech information, and no system information, which are specified by the MPEG standard so that a decoder does not perform decoding reproducing operation even if the area transferred to the decoder in the case where the end position of the effective AV data of an MPEG stream at a stop point of recording finish does not correspond to the end of the sector which is a unit of disk reading and-writing access, when the MPEG2 stream data is recorded on a disk-shaped recording medium.
