ABSTRACT:
A disc drive isolation system including an environment control enclosure and a disc drive isolation module is disclosed. A thermo-electric heat pump is mounted to the enclosure for cooling the interior of the enclosure and a fan circulates air within the enclosure. A humidity sensor controls the heat pump and the fan in response to the sensed humidity of the interior air. First and second temperature sensors control the heat pump andthe disc drive, respectively. The isolation module is disposed in the enclosure and has an outer body and an inner body supported within the outer body with the disc drive mounted within the inner body. The mounting of the inner body within the outer body sequesters the disc drive against vibration and shock applied to the outer body. This arrangement enables almost any disc drive to be operated in an industrial environment independent of the temperature, humidity, cleanliness, shock and vibration characteristics of the environment.
