Professional Disc (PFD) is a digital recording optical disc format introduced by Sony in 2003 primarily for XDCAM, its new tapeless camcorder system. It was one of the first optical formats to utilize blue laser, which allowed for higher density of data to be stored on optical media compared to infrared laser technology used in the CD and red laser technology used in the DVD format.

Famous quotes containing the words professional and/or disc:
“Never be intimidated when you deal with men. Curse, don’t cry.”
—Anonymous, U.S. professional woman. As quoted in Aspirations and Mentoring in an Academic Environment, ch. 4, by Mary Niles Maack and Joanne Passet (1994)
“Perhaps all music, even the newest, is not so much something discovered as something that re-emerges from where it lay buried in the memory, inaudible as a melody cut in a disc of flesh. A composer lets me hear a song that has always been shut up silent within me.”
—Jean Genet (1910–1986)
