Are there any considerations regarding the use of degaussers for secure data deletion ?
With reference to current international/industry best practices, the following are some major considerations/practices when using degaussers for secure data deletion: • The resistance of a magnetic media to demagnetization is the coercivity of the magnetic media and is measured in Oersteds. In order to completely erase the content on the magnetic media (e.g. hard disk), the degausser should produce a sufficiently strong magnetic field. It is recommended that the magnetic field should be at least 1.5 times higher than the coercivity of the media.
