![]() ![]() The magnetic field strength of a degausser is measured in gauss, or oersteds. Degaussers are rated for different media based upon the degausser’s maximum magnetic field strength. ![]() The most important aspect to consider when shopping for a degausser is its ability to erase your media. Some degaussers are meant for mobile operations, while others are built for high volume. Permanent magnet degaussers contain one or more rare earth magnets and do not require electricity to operate. Electromagnetic degaussers generate a magnetic field by charging a degaussing coil. With so many different degausser models on the market, it’s important to know what to look for when choosing a right model for your needs as not all degaussers are created equally. Basically, higher Oe media requires stronger degausser magnetic field ratings. The Oersted (Oe) value tells us how easy or how difficult a piece of media is to erase.All magnetic media has a magnetic property, called coercivity, that is also measured in units of oersteds (Oe).Degaussers contain a controlled magnetic field that is measured in units of gauss or oersteds (Oe).Degaussing is simply a demagnetizing process to erase a hard drive or tape.Using the right degausser will guarantee that your information is no longer retrievable. Degaussing is the guaranteed form of hard drive erasure, as such it serves as the standard method of data destruction. When exposed to the powerful magnetic field of a degausser, the magnetic data on a tape or hard disk is neutralized, or erased. WHY USE A DEGAUSSER/HARD DRIVE ERASER and OTHER FAQs WHAT IS A DEGUASSER?ĭegaussing is the process of reducing or eliminating an unwanted magnetic field (or data) stored on tape and disk media such as computer and laptop hard drives, diskettes, reels, cassettes and cartridge tapes.
