Sony XDCAMTM - Manual (Page 5)

File-based Disc Recording
In addition to its
impressive HD picture
quality, what makes
the XDCAM HD system
so distinguished is its
file-based disc recording
capability. This brings
huge benefits such as
instant random access
and IT connectivity,
to name just two.
Powerful Non-linear Recording
– the Professional Disc Media
The XDCAM HD products use a large-capacity
non-linear optical disc for recording, the PFD23
Professional Disc media, which Sony has developed
specifically for professional recording applications.
The Professional Disc is a 12-cm, single-layer,
reusable optical disc with a capacity of 23 GB. This
large capacity makes it possible to record up to two
hours* of HD material on a single disc. Professional
Disc media is highly reliable and durable because it
experiences no mechanical contact during recording
or playback, and is packaged into an extremely
durable and dust-resistant disc cartridge. The
non-contact recording and playback also makes it
an ideal media for long-term storage of AV assets.
Whereas traditional tape archive systems must be
rewound on a periodic basis to remove magnetic
powder debris, the Professional Disc media
completely eliminates this process.
Its reliability has already been demonstrated by the
SD version of the XDCAM products in various areas
such as ENG and EFP.
* The figure is approximate. The precise recording duration will depend
on the bit rate selected.
