include Sony's Securom ("fingerprint " has been saved in Data Subchannel),
New Securom ("fingerprint" has been saved in Data and Audio Subchannels),
LibCrypt (Sony's PlayStation) and LaserLock. The data saved in Subchannels

unreadable), d. none (both the data on Subchannels and normal bad blocks are
