What Wikipedia says

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.
