How Can I Safely Destroy Sensitive Data CDs/DVDs?

You have a pile of DVDs with sensitive information on them and you need to safely and effectively dispose of them so no data recovery is possible. What’s the most safe and efficient way to get the job done?

SuperUser reader HaLaBi wants to know how he can safely destroy CDs and DVDs with personal data on them:
