Professional Disc™ XDCAM
What is XDCAM Professional Disc? The XDCAM Professional Disc is a 12cm (5 inch) single-sided, rewritable optical disc that uses state-of-the-art blue violet laser technology. Despite its small size, the disc provides an amazing storage capacity of 23.3 GB - a feat made possible using a 405 nm blue-violet laser and an object lens with a 0.85 numerical aperture (NA) and specially developed recording layer. The XDCAM Professioanl Disc is able to attain high-density recording almost 5 times that of DVD using red-laser.
High Transfer-rate Recording
The specially designed, dust, shock,
and X-ray proof cartridge is constructed
to be compatible with the new dual optical
head recording system, enabling a maximum
transfer-rate of 144Mbps (using 2 optical
heads and 72Mbps (using 1 optical head). The
recording material in the disc has been
specially designed to have the sensitivity to handle
these high transfer-rates.This unique combination of
extensive recording capacity and high transfer-rate
capability positions the disc ideally for broadcast and professional
applications. The media will record approximately 85
minutes of SD content in DVCAM™ mode at 25 Mbps, and 120
minutes of HD content at 18 Mbps.
High Durability and Re-write Cycles
The Professional Disc provides the same features as standard optical formats, such as spilt
second random access and ENG/EFP ready durability, which is a result of the fact that the optical
head never touches the media. With the PFD-23 Professional Disc media, you can expect a
minimum of 1,000 read/write/erase cycles under specified operating conditions and can achieve
up to 10,000 read/write/erase cycles based on Sony testing done under ideal conditions (73
degrees F, 50% relative humidity). And with an archival life of over 50 years, the Professional Disc
is a highly durable, reliable option in recording media.
