Lesson plan
MagicGate
MagicGate (MG) was a copy-protection technology introduced by Sony in 1999 as part of the Secure Digital Music Initiative (SDMI). It worked by encrypting the content on the device and using MagicGate chips in both the storage device and the reader to enforce control over how files could be copied. MagicGate encryption was introduced with Sony's first digital audio players, with the related OpenMG technology being its software counterpart. Since then, the encryption has been rolled out to other Sony devices – it is used in the memory cards of the PlayStation 2 and, by 2004, was introduced into all of Sony's Memory Stick products. Some devices only accepted Memory Sticks which supported MagicGate. All Memory Stick Duo cards equipped with MagicGate can be identified by a notch located on the rear end of the card.
