Table 13. Magnetic flux density limits
6.1.4
Conductive noise
The disk drive shall work without soft error degradation in the frequency range from DC to 20 Mhz
injected through any two of the mounting screw holes of the drive when an AC current of up to 45 mA
(p-p) is applied through a 50-ohm resistor connected to any two mounting screw holes.
6.1.5
Magnetic fields
The disk drive will withstand radiation and conductive noise within the limits shown below. The test
method is defined in the Noise Susceptibility Test Method specification, P/N 95F3944.
