2.8.5

Shock

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.

2.8.5.1

Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum

operating shock of 70 Gs based on half-sine shock pulses of 2ms during read operations. Shocks should not

be repeated more than two times per second.

2.8.5.2

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 300 Gs based on a nonrepetitive half-sine shock pulse

of 2ms duration.

2.8.6

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.

2.8.6.1

Operating vibration

The maximum vibration levels that the drive may experience while meeting the performance standards speci-

fied in this document are specified below.

2.8.6.2

Nonoperating vibration

The maximum nonoperating vibration levels that the drive may experience without incurring physical damage

or degradation in performance when subsequently put into operation are specified below.
