Travelstar 80GN Hard Disk Drive Specification
34
6.5.1.2 Swept sine vibration
6.5.2 Nonoperating vibration
The disk drive withstands the vibration levels described below without any loss or permanent damage.
6.5.2.1 Random vibration
The test consists of a random vibration applied in each of three mutually perpendicular axes for a duration of
15 minutes per axis. The PSD levels for the test simulating the shipping and relocation environment is shown
below.
Note: Overall RMS (root mean square) level of vibration is 3.01 G rms.
6.5.2.2 Swept sine vibration
• 49 m/sec

(5 G) (zero-to-peak), 5 to 500 to 10 Hz sine wave
• 0.5 oct/min sweep rate
• 25.4 mm (peak-to-peak) displacement, 5 to 10 to 5 Hz
6.5.3 Operating shock
The hard disk drive meets the criteria in the table below while operating under these conditions:
• The shock test consists of 10 shock inputs in each axis and direction for a total of 60.
• There must be a minimum delay of 3 seconds between shock pulses.
• The disk drive will operate without a hard error while subjected to the following half-sine shock pulse
