On "Memory Stick" (continued)
What is "MagicGate"?
"MagicGate" is a copyright protection technology that operates when it is
provided in both the "Memory Stick" and the product in which the media
is used. A "Do you comply with "MagicGate"?" authentication takes place
between devices equipped with "MagicGate", and the "Memory Stick."
Data encryption takes places after the authentication. This unit is not
equipped with "MagicGate", so it can not record or playback the data
which needs "MagicGate".
