An HDTV digital video disk recorder which can record compressed HDTV signal and non-compressed 4ch audio signals for 32 minutes into a 30cm in diameter magneto-optical disk has been developed. This system is composed of HDTV codec and NTSC video disk recorder VF-200. The codec compress HDTV signal at 594Mbps to 94Mbps which is equal to effective NTSC data rate with intraframe DCT, Huffman coding and 2-stage bit rate control technique. The encoded data is recorded on the NTSC recorder VF-200 which is possible high density recording such as 1.6Gbits/In^2 and has the capacity of 23GBytes per disk.
