CD-R Test No. 1 Survival of correctly stored CDs


This is a list of all CD-Rs in my possession which have been recorded prior to 1999. The CDs have been tested with CD Check v. 1.1 using a Goldstar CD-ROM 8482B on July 5th, 2005. No errors were encountered.

Note that these are all CD-Rs I ever owned from that period (that is, it never happened that I throw away any CD because it was defective or unreadable). All CDs contain data (i.e. - not audio) and have been correctly stored during these years. All of them were kept in their jewel case and stored inside a closet, thus repaired from sunrays. However, except for their first years of life (until mid-2000), they were kept in a room exposed to cold temperatures in winter and to sumewhat hot periods during the summer (North of Italy). Level of humidity, also, might have been quite high in winter. They were rarely read or otherwise used, expecially after 2000.
