The top-end machine of the four (BDZ-X90), is expected to sell for about 200,000 yen ($1,752), roughly in line with Toshiba's flagship HD DVD recorder.
"With high-definition TVs spreading rapidly and more digital cameras and camcorders are becoming HD-ready, time is ripe for household recorders to move onto a next generation," Sony Executive Deputy President Katsumi Ihara told a news conference.
"We intend to make all our recorders in the domestic market Blu-ray compatible," he said.
Outside its home market, Sony is considering offering Blu-ray recorders in Europe, but the launch timing has yet to be decided.
Sony also today announced its new series of Blu-Ray recordable and rewritable media. This includes the new Sony 4x BD-R discs, as well as some printsble BD-R and BD-RE discs. All feature Sony's AccuCORE protection technology for increased durability.
