What is HD-DMD? High Definition Digital Multilayer Disk.
Quite simply, it is an optical disk with storage capacity
far superior to that of a DVD, 4.7GB vs. more than 20GB,
making HD-DMD ideal for high definition movie needs. By
using the reliable red laser and simply adding more layers
(like adding pages to a book), DDATA technology makes 20GB,
50GB, even 100GB disks a reality! Don’t be fooled
by imitations, authentic red laser multilayer technology
has arrived and it is brought to you by DDATA.
