Data destruction is a term that refers back to the removal or eradication of magnetic or optical computer storage media. The process of destruction varies, dependent upon the medium and method used in the process. The goal of data destruction is always to physically destroy the data in order to remove the chance of recovery.

This can be extremely highly relevant to businesses and corporations, where data might have information regarding the general public or others, for example clients. Similarly, confidential corporate information, including patent designs, business strategies as well as other sensitive data could be easily accessed by organizations in the event the details are not removed.

Like i said previously in the beginning, types of destruction vary, dependant on storage medium. For each and every storage medium, a variety of destruction techniques also exist.

This method doesn't eliminate the data, but makes recovery near impossible. However, elimination of the thin film that coats the very best side from the disk, by scraping, scouring or sanding will physically destroy the data. By comparison, the usage of microwave ovens, a less conventional technique, is highly effective due to the static charge and consequent arcing throughout the thin film storage layer of the disk.

Typical modern magnetic media constitutes tape backup units and difficult Disk drives. Unfortunately, tape backup units are incredibly hard to destroy, as a result of length of the tape, where a film of iron oxide layer retains the magnetic media. Shredding of these media is achievable, but requires significant financial investment in plant equipped to handle such devices. Acids, particularly, Nitric acid, at 50% concentration, will react violently with the iron oxide layer, destroying it entirely in minutes. However, this method demands the removing the outer plastic case to adequately expose the internal media storage tape. In some circumstances, incineration of the storage media might be a choice. However, this might inadvertently expose the operator to carenogens and may even be dissalowed certain countries.

Software driven destruction of hard drives is a highly efficient eradication technique which has been shrouded in urban myths, masking the actual ease that data may be permanently removed. In many instances, a single pass binary wipe (writing random zeros and ones to the drive) will permanently remove all data from your storage device. However, international standards exist, which all require more wiping processes, many of which will inadvertently bring about complete failure from the hard drive due to the high temperatures generated.
