The 8.9 kg RD-2000 is priced at 270,000 Yen (around $4400) and will go on sale in Japan on December 22.
The RD-2000 integrates a 30GB hard disk drive (HDD) and a 4.7GB DVD-RAM drive. It allows users to record up to 33.5 hours of video images.
TV programs can be edited between the HDD and DVD-RAM into separate sections or chapters. You can then access recorded chapters by on-screen thumbnails. A library system holds the title information of all chapters recorded on the DVD-RAM to help find target discs.
Users also have the option of rewinding and playing a program from the start while it is still being recorded. When record is pressed, it starts taping to the remainder of the HDD capacity, even without a DVD-RAM disk.
