The discs are reliable and robust, suitable for field work (something which has previously been a problem with many disc-based systems).
Sony maintains that different formats within XDCAM family have been designed to meet different applications and budget constraints.
The XDCAM range includes cameras and decks which act as drop-in replacements for traditional VTRs allowing XDCAM discs to be used within a traditional videotape-based workflow.
