Sony is working on creating a 1.3GB double density CD, which with time will be available in commercial duplication CD-ROM, CD-R and CD-RW formats. The double density name is described by Sony as a "tentative" choice. If used the discs are likely to end up with the unwieldly acronym of DDCD-ROM, which sounds to Digit like a cyborg hooker from a low-budget Bladerunner rip-off. The DDCDs utilize the same base specifications as conventional CDs. Sony has miniaturized the track-pitch and minimum pit length to increase data density. The address format has also been expanded. Unlike CDs the DDCD will include facilities for a copy control system for content protection.
