Enhanced Ruggedness
-------------------
Notebook, subnotebook and handheld computers used in mobile field
applications must be capable of surviving a high degree of shock and
vibration due to the often unpredictable and adverse conditions
under which they are operated. Int gral's products address these
requirements with a unique ramp loading mechanism for loading and un-
loading the heads without touching the media, providing several
benefits relating to ruggedness, reliability and low power
consumption. Int gral's dynamic ramp loading technology represents an
innovative approach to solving the environmental challenges of 1.8
inch disk drive engineering by virtually eliminating the possibility
of head slap in the power down state when the drive has been re-
moved from the system. As a result, Int gral's drives can withstand
greater than a 500G shock force in the non-operating mode. The
benefits of ramp loading perhaps can best be illustrated by the
start/stop specification of Int gral drives: a minimum of 250,000
successful start/stops is guaranteed, while a conventional contact
start/stop drive typically specifies only 40,000.
