Chief technology officer for Sony Music Phil Wiser, describing Sony's new copy-protected CDs which contain tracks that play on ordinary CD devices, but not a PC; a second set of files, which will only play in a computer if the original CD is in the drive; and a third set of digital files, compressed in a proprietary Sony codec which users can upload to a portable only if it is a Sony-licensed audio device.
