Our customers are pretty familiar with shredding and e-recycling activities. But what about other ways of destroying data—like degaussing?
About the process
Degaussing: How it works
The amount of coercivity in a magnetic material determines how much it resists changes to its magnetization. The more powerful degaussing equipment you have, the easier this process will be for your company’s data storage disks; however some media with higher levels can still prove challenging if not done correctly. Using appropriate techniques like stronger magnets or reducing their power output (wattage) is the best way to do it.
Types of degaussers
• The coil degausser consists of a steel core surrounded by copper wire. Alternating current sets up an electromagnetic field which is best used for demagnetizing hard drives and other magnetic storage media.
• The capacitive discharge degausser is a device that stores electrical charge in a capacitor. The energy is discharged in a high-frequency electromagnetic pulse, which demagnetizes storage media and destroys the data.
• The permanent magnet degausser is a rare-earth magnet used for degaussing magnetic media like tapes and hard drives without the need for an electrical charge.
As a media sanitation choice, degaussing is an older technique. Success depends on matching the type of degausser to the need. This equipment can only sanitize magnetic storage media, and there is limited scalability. It is primarily suited to managing end-of-life media, but its environmental impact is high. There can also be high operational costs associated with its use.
If you want to get rid of electronics you no longer use, think about the benefits of recycling e-waste. For example, our government joins others in the effort to keep harmful e-waste out of landfills. This kind of recycling also reduces the need to mine materials from the earth. At our company, we encourage e-recycling because it’s good for the planet in general and ultimately, makes the electronic gadgets we all need more affordable.
