Panasonic is making a concerted effort to see DVD-RAM take off more widely outside Japan, where it has enjoyed huge success. DVD-RAM is one of the formats, alongside DVD-R and DVD-RW, that is supported by the 219-strong DVD Forum. The big advantage of DVD-RAM over DVD-R/-RW (and the DVD+R/+RW formats supported by the 55-member DVD alliance) is that it does not require special burning software: files can be dragged and dropped using any file manager utility. A second advantage is the durability: DVD-RAM discs can be rewritten up to 100,000 times -- in contrast to the 1,000 rewrites supported by DVD-RW and DVD+RW standards.
