刻录在CD-R光盘上的数据,其存档寿命是衡量CD-R光盘质量的一项重要指标。然而目前对CD-R光盘的寿命,制造商提供的数据是30到300年;但有些用户反映,录入光盘的数据只经过几星期或几个月就不能再读出。为此对CD-R寿命的实验测定,应有一个统一标准。一.影响CD-R光盘寿命的因素 1.材料:包括对盘基(聚碳酸酯)、染料记录层(花菁或酞菁等)、金属反射层(金、银或银合金)及保护层(UV固化胶)等原材料的选择。例如:染料的稳定性、酞菁优于花菁,目前已有改进型酞菁和花菁染料。又如金属反射层的抗衰变,金稳定性
The data recorded on a CD-R disc is an important indicator of CD-R disc quality. However, at present, the data provided by the manufacturer for the life of a CD-R disc is between 30 and 300 years; however, some users report that data recorded on a disc can not be read out after only a few weeks or months. To this end of the CD-R test of life, there should be a uniform standard. 1. CD-R CD-R affect the life of the material 1. Materials: including disc base (polycarbonate), dye recording layer (cyanine or phthalocyanine, etc.), the metal reflective layer (gold, silver or silver alloy) and the protective layer (UV curing glue) and other raw materials of choice. For example: the stability of the dye, phthalocyanine is superior to cyanine, there are already improved phthalocyanine and cyanine dyes. Another example is the metal anti-decay layer, gold stability
