Sony XDCAM 50GB Dual Layer Disc- PFD50DLAX
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.
The PFD50DLA Dual Layer XDCAM Disc offers up to 4 hours and 8 minutes of recording time, in multiple HD and SD formats. Here are the compatible formats and recording times for each mode:
- XDCAM MPEG HD422 @ 50 Mbps: 95 min.
- XDCAM HD @ 35 Mbps: 145 min.
- XDCAM HD @ 25 Mbps: 190 min.
- XDCAM HD @ 18 Mbps: 248 min.
- MPEG IMX @ 50 Mbps: 100 min.
- MPEG IMX @ 40 Mbps: 120 min.
- MPEG IMX @ 30 Mbps: 150 min.
- DVCAM @ 25 Mbps: 185 min.
The PFD50DLA is for use with the XDCAM HD hardware, including the PDW-F355, F335, and F75. These discs are also compatible with XDCAM MPEG HD422 Products: PDW-700, HD1500, and U1.
Phase Change Technology
Professional discs from Sony use a unique phase-change recording material to support higher read/write speeds. Professional discs also support access by two simultaneous pickups. In phase change recording the recording layer must change from a crystalline (high reflectivity) phase to amorphous (low reflectivity) phase fast enough to enable transfer speeds of up to 72 Mbps.
XDCAM discs are made of polycarbonate with a polypropylene case. The protective cartridge keeps the disc and data safe from debris, rough handling, shock, and x-rays. XDCAM discs are also resistant to heat and humidity. These factors make XDCAM ideal for harsher environments, while also allowing for long media life and long term storage.
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.**
