Subject: [ARSCLIST] Temperature Requirements for CDs and digital media

Can anyone tell me what, if any optimal conditions are required for CDs
and digital media?  I know there are specific temperature requirements
for magnetic media and film but I don't know if there are any conclusive
recommendations for digital formats.  Is there an answer to this
