High Density Recording Sonys Professional Disc recording media is a 5 inch (12cm) rewritable optical disc capable of recording in two layers up to 50GB (or up to 23.3GB on the single-layered disc). By achieving a track pitch of 0.32 m, with state-of-the-art manufacturing technology and by utilizing bluelaser technology, this type of disc media can attain high density recording more than 10 times (or 5 times on a single layer disc) that of a DVD (4.7GB) using red-laser technology. High Transfer Rate and Long Recording Times The specially designed, dust, shock and X-ray proof product is constructed to be compatible with the new dual optical head recording system, enabling a maximum writing transfer rate of 172 Mbps (using two optical heads) and 86 Mbps (using one optical head). The dual layer media will record approximately 190 min. (85 min. in the single layer disc) of SD content in DVCAM mode at 25 Mbps and 270 min.
