12 Medalist 3240 and Medalist 2531 Product Manual, Rev. A

1.8.5Shock

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.

1.8.5.1Operating 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.

1.8.5.2Nonoperating 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).

1.8.6Vibration

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.

1.8.6.1Operating 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)
