Professional Disc Systems - Sony XDCAM PDW-U1 Brochure

■
Flexible Platform
The Professional Disc system is a very flexible platform
on which an assortment of data in a variety of formats
can reside. The use of optical disc technology
eliminates the restrictions inherent in proprietary tape
footprints, and allows a variety of different video
formats to be recorded as 'data files', and is therefore
extremely flexible as to what can be recorded to it. In
addition to video and audio streams, you can record
a variety of metadata, such as date/time information
and comments indicating the material content.
Furthermore, computer files created on Microsoft
Word, PhotoShop, and other application software can
also be stored on a Professional Disc media*.
*Up to 500 MB
■
Largest-Capacity Optical Disc
The superior disc capacity of the Professional Disc
enables you to make high-quality yet long-duration
recordings. Its 23.3-GB data capacity translates to a
recording time of 45 to 85 minutes depending on the
bit rate the camera operator chooses.
■
High Transfer Rate
The Professional Disc's data transfer rate is 86 Mb/s
from a single optical head unit and 172 Mb/s on a
dual head deck, providing stable recording and
playback of high bit rate data such as a 50 Mb/s
MPEG IMX stream.
■
Quick Random Access
The nonlinear nature of the Professional Disc alone
provides tremendous benefit when
handling audio/video content. When a recording is
played back from the disc, its physical location on the
disc does not impact the time required to access it.
Recordings can be accessed in a fraction of the
equivalent time taken to access information on disc,
making it much easier and faster to locate source
material. This is the beauty of random access, and all
Sony XDCAM products are equipped with powerful
features – delivering innovation to all your programming
operations.
■ Highly Reliable, Durable and
Re-usable Medium
Optical discs have a natural advantage since they suffer
no mechanical contact during recording or playback,
making the format ideal for continuous use and re-use.
The Sony Professional Disc is highly resistant to dust, shock
and scratches, and is packaged in an extremely
durable and dust-resistant cartridge.
It is resistant to heat and humidity, and is X-ray resistant
– factors that make the Professional Disc ideal for use
in harsh field environments, and also allows for long
media life and long-term storage.
