Destruction of obsolete information may involve shredding of paper-based data. Higher security may require burning. For electronic media, formatting with a secure erase (overwriting with a random pattern of zeros and ones) may be acceptable. Other security measures may involve using a strong electromagnet such as a bulk tape eraser. Higher security (for example some DOD requirements) may demand the opening of a hard drive and filing the metal on the platters.
