The mod must&amp;#x27;ve been too young to ever used a CD-R. That was kind of shocking to me, but then I haven&amp;#x27;t used CD-R myself in almost a decade.</text><parent_chain></parent_chain></comment><story><title>Understanding CD-R and CD-RW (2003) [pdf]</title><url>http://www.osta.org/technology/pdf/cdr_cdrw.pdf</url></story>
