BeAll releases 4.85GB extended capacity DVD-R discs


It seems that BeAll has improved their production technology for DVD-R disks. According to eMediaLive, BeAll released a new, so called DVD-R EX (Extreme eXtended) with a recording capacity of 4.85 GB.


Compared to regular DVD-R disks with a capacity of 4.7GB is this new media “ideal for two-hour DV-tape video transfers, personal backup of DVD-videos, and especially for DVD games which are sometimes a little larger than regular 4.7GB disks”, said BeAll’s general manager Seong-Joom Kim.

For those who think that these disks are out of spec, they say that the DVD physical format specifications allow some manufacturing leeway. Ways to increase the capacity of a disk are the reducing of the track pitch, decreasing the disk channels bit rate (scanning velocity) and the adjustment of the end radius of the programm area which is normally 58mm. But all these changes can cause compatibility problems with DVD-Rom drives.

“It was very difficult to increase the storage capacity while maintaining compatibility with existing drives but after a lot of trial and error we succeeded in optimizing these physical parameters within DVD Forum specifications.” said Kim.


Who doesn’t need additional data storage space? BeAll Developers answers the call with its new EX (Extreme eXtended) DVD-R disc featuring an enhanced capacity of 4.85GB. Priced at a premium over standard media, 4X DVD-R EX is currently available while 16X is still in the works

The additional capacity afforded by DVD-R EX, says BeAll’s general manager Seong-Joon Kim, makes the media “ideal for two-hour DV tape video transfers, personal backup of DVD-Videos, and especially for DVD games which are sometimes a little larger than regular 4.7GB discs.” For content creators authoring DVDs from scratch, the added space accommodates roughly four more minutes of typical-quality audio and video. More sophisticated titles will benefit from less compression, an additional audio track, supplementary material, motion menus, subtitles, or even some DVD-ROM content

It looks like BeAll was really able to manage all the problems and now have a working DVD-R media with higher capacity that also corresponds to the specs.

Of course, there are some people out there that are interested in such medias. But it remains to be seen if this kind of medias from a company not always known for high quality, will become widely accepted in the market.
