Gold Disc
The recordable disc used in recordable CD systems. The blank disc is made of a bottom layer of polycarbonate with a preformed track spiral which the recording laser follows when inscribing information onto the disc. This type of disc is therefore also called pre-grooved. A translucent layer of recordable material is laid on top of the polycarbonate, then a reflective layer of gold. On top there are thin layers of lacquer and label.
GPF

GPP
Generic Packetized Protocol. A method for transferring groups of data that is independent of the type of hardware used, hence the name generic.
