1.8.5
Shock
For all shock specifications, it is assumed 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. For the nonoperating specifications,
it is assumed that the read/write heads are positioned in the shipping
zone.
Note. At power-down, the read/write heads automatically move to the
shipping zone. The head assembly parks outside of the maxi-
mum data cylinder. When power is applied, the heads recalibrate
to Track 0.
1.8.5.1 Operating
shock
The Medalist 3240 and the Medalist 2531 will comply with the performance
levels specified in this document when subjected to a maximum operating
shock of 5.0 Gs (based on half-sine shock pulses of 11 msec, as specified in
MIL-STD-202F). Shocks are not to be repeated more than two times per
second.
1.8.5.2 Nonoperating shock
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when sub-
sequently put into operation is 75 Gs (based on nonrepetitive half-sine
shock pulses of 11 msec duration, as defined in MIL-STD-202F).
1.8.6
Vibration
For all vibration specifications, it is assumed 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. For the nonoperating
specifications, it is assumed that the read/write heads are positioned in
the shipping zone.
1.8.6.1 Operating
vibration
The following table lists the maximum vibration levels that the drive may
experience while meeting the performance standards specified in this
document.
5–22 Hz
0.020 inches displacement (peak to peak)
22–350 Hz
0.50 Gs acceleration (zero to peak)
