All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock
may be applied in the X, Y or Z axis.
2.6.4.1
Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs
(read) and 40 Gs (write) based on half-sine shock pulses of 2ms. Shocks should not be repeated more than two times per second.
2.6.4.2
Nonoperating shock
The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when
subsequently put into operation is 250 Gs based on a nonrepetitive half-sine shock pulse of 2ms duration.
2.6.5
Vibration
All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws.
Vibration may be applied in the X, Y or Z axis.
2.6.5.1
