Why do home made CDs andDVDs retain data for a short time?
I guess most of you have experienced the CD-R or DVD-R that you burned a few years ago that has no data on it now. The logic is strange; Windows says there is no data on the disc so I try to write, it then says the disk is full!!
What happens to the data does it evaporate? I mean a laser burnt the data into the metal layer if the disk, where have these indentations/grooves gone?
