CD-R如何可以循環再用？

CD-R可以循環再用.......

i try that before, but not for the used CD-R
for the new one... you can just copy the file to the disk from window, but dun burn it in the disk,then the CDR will have that file,
but not a burned data
so u can re-use it
but if u process the buring process, it cant be recycle like this!

CD-R 其實真係冇辨法再用嫁. 循環再用就最多係交隻用完ge CD-R去回收商, 佢地會壓碎當普通膠ge物料熔左佢去再做翻膠類產品咋

而自己平時燒 CD-R 就最多係唔夠 650MB data 時唔 close隻碟 等下次再燒 data 落去 到隻碟夠 650MB 時先 close 佢 用盡佢 D 儲存空間囉
