目前,CD-R(CD-Recorder)刻录机已经非常普及,价格电越来越便宜,制作自己的光盘已经不是遥不可及的事情了。为了更好地使用它,对CD-R盘片有一个全面的认识是十分常必要的。 一、CD-R盘片的基本结构 CD-R标准是飞利浦公司于1990年制定的。被称作橙皮书Part Ⅱ。CD-R技术目前应用非常广泛,由于其记录成本非常低.每兆字节不到3分钱。在数据备份与交换、多媒体应用、桌面出版等众多领域得到了广泛的应用。 CD-R盘片的片基与传统的CD盘片基本一样,但表层的“刻痕”不同。在传统CD片上有螺旋状的轨道(Track),而这些轨道又是由很多不连续的凹槽所组成,这些凹槽是用激光“雕刻”成的,又称之为“坑”(Pits),坑与坑之间的地方称为“岛”(Land)。在CD-R盘片上以连续的槽沟(Groove)取代“坑”,并组成螺旋状的轨道(Track),而“坑”就被记录在这些槽沟内。在空白的盘片
At present, CD-R (CD-Recorder) recorders have become very popular, the price of electricity is getting cheaper, making your own CD-ROM is no longer out of reach. In order to make good use of it, it is often necessary to have a thorough understanding of the CD-R disc. First, the basic structure of CD-R disc CD-R standard Philips company in 1990 enacted. Known as the Orange Book Part II. CD-R technology is widely used today due to its very low recording costs of less than 3 cents per megabyte. In the data backup and exchange, multimedia applications, desktop publishing and many other fields have been widely used. The base of a CD-R disc is basically the same as a conventional CD disc, but the “notch” of the surface layer is different. Traditionally, CDs have a spiral track, which in turn consists of many discontinuous grooves that are “engraved” by the laser, also known as “pits” The place between the pit and the pit is called the “Land.” The CD-R disc replaces “pits” with continuous grooves and forms a spiral track, where “pits” are recorded. In the blank platters
