INTEGRAL PCMCIA DRIVES

 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.
