MagicGate
From Wikipedia, the free encyclopedia
MagicGate is a copy-protection technology introduced by Sony in 1999 as part of the Secure Digital Music Initiative (SDMI). 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.
MagicGate encryption is used in the memory cards of the PlayStation 2 and, as of 2004, has been introduced into all of Sony's Memory Stick products. Some devices, such as Sony's Network Walkman, will only accept Memory Sticks which use MagicGate technology.
All Memory Stick Duo cards equipped with MagicGate can be identified by a notch located on the rear end of the card.
[edit] Support
Few (USB or PCMCIA) Memory Stick compatible card readers actually support secure MagicGate. Though it seems most manufacturers list Memory Stick Pro/Pro Duo (MG) compatibility (with MG meaning MagicGate) it seems they don't necessarily support the security portion of MagicGate (even Sony itself does not on certain readers) so caution is be advised when purchasing a card reader/writer for use with SonicStage (Sony CONNECT). Non-MagicGate memory card reader/writers DO NOT show up in SonicStage, with the notable exception of Sony Ericsson phones.
Current Sony devices that DO support MagicGate DRM as of summer 07:
-Most Memory Stick capable Sony VAIO notebooks and desktops
-PlayStation Portable
-PlayStation 3
-MSAC-US40 USB Memory Stick Card Reader/Writer.
Current Sony Devices that DO NOT support MagicGate DRM as of summer 07:
-Mylo Personal Communicator* (Mylo's 1GB internal memory can be used with SonicStage and supports OpenMG.)
-All U.S. Sony Ericsson phones (most Sony Ericsson phones should show up in SonicStage for MP3/AAC transfer.)
-VGP-MCA10 PCMCIA Card Reader/Writer (does not sport the MagicGate logo.)

-Sony 17 in 1 Card Reader/Writer MRW62E/S1/181

* Indicates MagicGate MAY BE possible via future firmware updates.
Important MagicGate Announcement --
As of 09-11-05, the future of MagicGate DRM is known. Sony Electronics has announced that as of March 2008 they will be 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. The continued development of the SonicStage software past version 4.3 and support for MagicGate DRM is as yet unknown.
