ABSTRACT:
An information storage apparatus is disclosed for reading and/or writing information on a rigid storage medium which includes a liquid bearing interface between the transducer and medium instead of a conventional air bearing. The liquid is a fluorocarbon which has stable, self-lubricating, viscous and high-density properties. In an exemplary embodiment of a cockpit voice recorder/flight data recorder, low-density metallic components or composite parts of the rigid magnetic disk drive assembly with essentially the same density as the liquid achieve a near zero buoyancy configuration that obviates the effects of vibration and acceleration.
