DVD-R和DVD+R盘有什么区别（国外英文资料）Lets take a look at how to buy cd-r/RW, DVD plus or minus R/RW.Cd-r/RW articleKnow the cd-r/RW discCd-r is a cd-rom that can be read multiple times. Cd-rw is a compact disc that can be burned multiple times and repeatedly. Although cd-r disc looks just a thin disc, but in fact it is composed of five layers, they respectively are: dish at the grass-roots level, dye, reflector, coating, printing layer. The bottom layer is the thickest, which is composed of high temperature resistant, moist, high strength PC plastic.The dye layer, the layer of data that records data, has three types of dyes, Cyanine, Phthalocyanine, and AZO. The reflected layer, the layer of reflected laser light, is composed of silver and other chemicals.Protecting the data of the dye layer by using anti-ultraviolet and wear-resistant media. Printing layer, this is what we see the cover of the CD, good printing layer should have wear-resisting, tensile and corrosion resistant properties, printing layer to protect the discs in the security of data. Cd-rw and cd-r, cd-rw is divided into seven layers: dish at the grass-roots level, dielectric layer, dye layer, dielectric layer, reflector, coating, printing, it USES the inverter of chemical materials in order to realize many times burn.Cd-r disc dyesDye layer is one of the most important in cd-r discs layer, is used to record data, dyestuff layer used in a total of three kinds: : Cyanine Cyanine, titanium qingsong (Phthalocyanine) and metallization AZO compounds (AZO). And what about the green, platinum, gold, and blue dishes we used to call?Green dish is actually USES the disc of the (Cyanine dye), photoluminescence itself is green, blue and reflector combination after appear green, however, so make the CD also green.
