Another manufacturer, ECHO Tape, offers 100% certified tape media.  

Certified Tape Media
Certified tape media is simply magnetic tape media that is being reused.  Currently, there are many definitions of what constitutes certified tape media.  Different levels of testing exist to verify the condition of used tape media, and there is no one universal standard to which tape media is held to be considered certified.

The ECHO Difference
Media can only be considered ECHO 100% Certified after having endured rigorous testing and having met ECHO’s strict standards of zero hard errors, zero fatal errors, and zero server track errors on each tape carrying the ECHO name.  ECHO guarantees that every single track of data on every ECHO tape has been overwritten, read, and guaranteed free of such errors; setting an unmatched precedence for reliability.
