White book CD-ROM
     
         A more open {CD-ROM} {standard} than
        {Green Book CD-ROM}.  All films mastered on CD-ROM after March
        1994 use White Book.  Like Green Book, it is {ISO 9660}
        compliant, uses mode 2 form 2 addressing and can only be
        played on a {CD-ROM} drive which is {XA} (Extended
        Architecture) compatible.  White book CDs are labelled "Video
        CD".
