The Datawrite Yellow 16x DVD-R has evolved from it`s 4x and 8x predecessors. Datawrite Classic 16x Yellow Branded DVD-R in Packs of 50 is a DVD recordable format. A DVD-R typically has a storage capacity of 4.71 GB (or 4.38 GiB). The larger storage capacity of a DVD-R compared to a CD-R is achieved through smaller pit size and smaller track pitch of the groove spiral which guides the laser beam. Consequently, more pits can be written on the same physical sized disc. In order to write smaller pits onto the recording dye layer a red laser beam with a wavelength of 640 nm (for general use recordable DVD, versus a wavelength of 780 nm for CD-R) is used in conjunction with a higher numerical aperture lens. Because of this shorter wavelength, DVD-R use different dyes from CD-R to properly absorb this wavelength.
