Sony is introducing “Sterile Burning” where owners of CDs can only burn one copy, but not copy of copies. Holding the shift key on CD insert or using a non-Windows OS will likely get around all this. The technology Sony is testing, which was developed by a UK anti-piracy firm, First4Internet, allows for copying ripped and burned tracks from a copy-protected disc to a blank CD in WMA format. The DRM on the disc remains intact and prevents the CD from being duplicated. Link.
