CD这个词在外行人眼里,不过是一张音乐光盘,而且谈到这个话题往往还与盗版联系在一起。为什么呢?因为盗版CD又便宜又好用。而在广告公司里,CD则是创意部至高无上的统帅(创意总监英文Creative Director的缩写),带领着一堆小朋友们,一起“拼搏厮杀”。虽然两者都可称为CD,但这两者诞生所要具备的条件却天壤之别。一张光盘CD本质上是塑料片,只是激光射线把盘片面烧上无数个代表数据的凹点,用一凹一平来代表二进制中的0和1。 CD in the eyes of laymen in the eyes of the eyes, but a music CD, but also talked about this topic often associated with piracy. Why? Because pirated CD is cheap and easy to use. In advertising agencies, CD is the supreme commander of the creative department (Creative Director in English Creative Director acronym), led a bunch of children, together, “fight hard.” Although both can be called CDs, the conditions for the birth of both are vastly different. An optical disc CD is essentially a plastic sheet, except that the laser beam burns a number of pits representing innumerable data pits. A concavity and a flatness represent 0 and 1 in the binary.
