MagicGate (MG) is a copy-protection technology introduced by Sony in 1999 as part of the Secure Digital Music Initiative (SDMI).[1] [2] It works 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 are copied.[3]
MagicGate encryption was introduced with Sony's first digital audio players, with the related OpenMG technology being its software counterpart.[4] Since then, the encryption has been rolled out to other Sony devices – it is used in the memory cards of the PlayStation 2 and,, has been introduced into all of Sony's Memory Stick products. Some devices will only accept Memory Sticks which use MagicGate technology.[5]
All Memory Stick Duo cards equipped with MagicGate can be identified by a notch located on the rear end of the card.
Few (USB or PC Card) Memory Stick-compatible memory card readers support secure MagicGate. Although manufacturers list Memory Stick Pro/Pro Duo (MG) compatibility, where MG means MagicGate, they may not support the security portion of MagicGate. This becomes important when purchasing a card reader/writer for use with SonicStage and Sony CONNECT as even Sony itself does not fully support MagicGate on certain readers. Non-MagicGate memory card reader/writers do not show up in SonicStage, with the notable exception of Sony Ericsson phones.

In March 2009, Sony Electronics announced they were phasing out the Sony CONNECT service in favor of Windows Media Audio & Windows Media DRM, though they have not officially announced plans to continue a Windows Media DRM music service, either. As of June 2009, the future of MagicGate DRM was unknown. MagicGate slots were still a part of the default Vaio configuration as of May 2010.
