Two Types of Nonlinear Recording Medium –
The Professional Disc and SxS PRO Media
Through detailed analysis of an optimum workfl ow for various types of production applications,
Sony has selected two types of nonlinear recording media for the XDCAM family –
optical disc and memory card. The XDCAM HD422, XDCAM HD and XDCAM SD lineup use
an optical disc medium, called Professional Disc media, which offers large storage capacity of up to
50 GB at an affordable price. The XDCAM EX lineup uses a memory card, the SxS PRO™ card,
having a highly compact design because the card itself is so slim, as well as offering data
transfer rates of up to 800 Mb/s.*
Both product lines – disc-based products and memory card-based products – deliver the same
tremendous benefi ts of a nonlinear workfl ow, including fi le based recording, an instant
random access capability, a thumbnail search capability, no overwriting on existing footage,
and IT/network capability.
*This data read speed is measured with benchmark software. Actual data transfer speeds vary according to measurement conditions.

The Professional Disc Media
The Professional Disc medium adopted in the XDCAM HD422,
XDCAM HD and XDCAM SD lineup uses state-of-the-art
blue-violet laser technology to enable extremely large-
capacity recordings. The diameter of the Professional Disc
media employed is a mere 12 cm, equal to that of other
optical media such as CDs and DVDs. Yet, despite its small
size, this disc provides an amazing storage capacity of 50
GB (PFD50DLA dual layer disc)/23.3 GB (PFD23A single layer
disc), yet it is offered at a very affordable price.
Extraordinary storage capacity in a 5-inch (12-cm)
