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.
Notably very 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 should be advised when purchasing a card reader/writer for use with SonicStage (Sony CONNECT) and a PSP or MYLO.
The MSAC-US40 currently listed at SonyStyle.com (As of 01-23-07) is compatible with ATRAC files hence it does support secure MagicGate transfers.
