          Degausser creates strong magnetic field and using the coercive force
          to destroy the data. It is known as very strong data destroying
          method.
           
          This equipment uses maximum 15,000 gauss and magnetically destroy
          hard-disk in 40mins.
         
          In addition, after the degaussing process the hard-disk is unable to
          reuse.
           
          It is a very strong destroying method, but when you do the second
          process which is the pressure crush or shredding (physical
          destruction), that would complete a better process.
           
          ※ Double Crush: Degaussing+Pressure Crushing or
              Degaussing+On-site Shredding
