5.5 Vibration and Shock

All vibration and shock measurements in this section shall be for the disk drive without the mounting attach-
ments for the systems. The input level shall be applied to the normal drive mounting points.

5.5.1 Operating Vibration

The disk drive will operate without a hard error while being subjected to the following vibration levels.
5.5.1.1 Random Vibration
The test will be 30 minutes of random vibration using the power spectral density (PSD) levels specified in
C-S 1-9711-002 (1990-03) as V5L. The vibration test level for V5L is 0.67G RMS (Root Mean Square).

5.5.1.2 Swept Sine Vibration
- 1 G (Zero to peak), 5 to 500 to 5 Hz sine wave
- 0.5 oct/min sweep rate

5.5.2 Non-Operating Vibration

5.5.2.1 Random Vibration
The test consists of a random vibration applied in each of three mutually perpendicular axes with the time
duration of 15 minutes per axis. The PSD levels for the test simulates the shipping and relocation environ-
ment which is shown below.
