The proportion of DVD recorders sold that were next-generation rose from 6.1 percent in October to around 20 percent in November and December, said the study by Japan's Business Computer News think tank released Thursday.
Due to the price difference, next-generation DVDs made up a lucrative 35 percent of the total value of DVD recorder sales in the last two months of 2007, it said.
Blu-Ray accounted for a crushing 90 percent of next-generation DVD recorder sales in the three-month period, the study said.
Three Sony models were the top-selling next-generation DVD recorders, with the electronics giant accounting for some 60 percent of total sales in the sector.
Panasonic took 27 percent of sales, with Sharp Corp. coming in third at nearly 10 percent. Both Matsushita and Sharp support Blu-Ray.
Toshiba enjoyed four percent of the sales, the study said.
