Dual Layer 50GB Rewritable Optical Disc For XDCAM 185 min
Sony's new Professional Disc recording media is a 5 inch (12cm) rewritable optical disc capable of recording in single, sided (23GB) or two layers (50GB). By achieving a track pitch of 0.32 m, with state-of-the-art manufacturing technology and by utilizing blue-laser technology, the disc media can attain high density recording more than 5 times (23GB) or 10 times (50GB) than that of a DVD (4.7GB) using red-laser technology.
Sony PFD50DLA - 50G Dual Layer Disc
Sony's new Professional Disc recording media is a 5 inch (12cm) rewritable optical disc capable of recording in two layers (50GB). By achieving a track pitch of 0.32 m, with state-of-the-art manufacturing technology and by utilizing blue-laser technology, the disc media can attain high density recording more than 10 times (50GB) than 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. of SD content in DVCAM mode at 25 Mbps and 270 min. of HD content in MPEG mode at 18 Mbps. This unique combination of extensive recording capacity and high transfer rate capability ideally positions the disc for broadcast and professional applications.
High Writing Speed for Linear Editing Capabilities
When used with the software upgrade for the PDW-1500 for new linear editing functions, the writing speed of the disc is increased to 2.4 times of the previous PFD23. These new editing functions allow the user to perform Assembly edits and Video Insert edits.
High Durability and Re-write Cycles
The Professional Disc provides the same features as standard optical formats, such as split-second random access and ENG/EFP-ready durability, which is a result of the fact that the optical head never touches the media. With both models of the Professional Disc media, you can expect a minimum of 1,000 read/write/erase cycles under specified operating conditions. And with an archival life of over 50 years, the Professional Disc is a highly durable and reliable option in recording media.

The Sony XDCAM Professional Disc now offers twice the storage space with 50 Gigabytes and dual layer recording capacity. The new dual layer disc, model PFD50DLA, offers 50GB of storage capability. Though the same size as a DVD or a CD, the XDCAM professional disc uses a blue-violet laser to provide amazing storage possibilities.
Professional users can record up to four hours and 30 minutes of HD content on the dual layer disc when shooting in MPEG HD 4:2:0 mode at 18 Mbps, three hours and 20 minutes at 25 Mbps, and two hours and 30 minutes at 35 Mbps. In DVCAM mode users can record about three hours and 10 minutes of content on the new disc.
The PFD50DLA is for use with the XDCAM HD products coming soon, including the PDW-F355L camcorder, PDW-F75 deck, and PDW-U1 drive unit.
Users can expect a minimum of 1,000 read/write cycles and 1,000,000 read cycles, under specified operating conditions. According to Sony research, archival life is expected at 50 years. Recommended archival temperatures are 68 degrees Fahrenheit and 40% relative humidity.
The XDCAM disc is a flexible platform, able to accommodate an assortment of data in a variety of formats. Optical disc technology does not have the limitations that come with tape and therefore can allow a variety of different formats to be recorded as "data files". The professional disc is very flexible with what can be recorded to it. Along with video and data streams, a variety of metadata, such as date/time information and comments notating material content, can be recorded to the disc as well. Computer files created on Microsoft Word, Photoshop, and other application software can also be stored on the XDCAM professional disc media.
