Features

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 unloading 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 removed 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.
