1.10.5 Shock and vibration
All shock and vibration specifications assume that the drive is mounted
as recommended in Section 2.5 on page 23, with the input levels
measured at the drive mounting screws. Shock measurements are
based on an 11 msec, half sine wave shock pulse, not to be repeated
more than twice per second.
During normal operating shock and vibration, there is no physical dam-
age to the drive or performance degradation. During nonoperating shock
and vibration, the read/write heads are positioned in the shipping zone.
During abnormal operating shock and vibration, there is no physical
damage to the drive, although performance may be degraded during the
