ABSTRACT:
A method and apparatus including a system for recirculating liquid in a controlled environment. In one aspect, a method for recirculating a liquid bearing material in an information storage apparatus is provided. The method includes providing a wick in a housing, the wick having pores of a selected size; placing the wick in contact with a storage medium; providing a quantity of liquid bearing material in the housing sufficient to maintain a desired quantity of fluid at the interface between the storage medium and an interactive element and to saturate the wick; and moving the storage medium to induce capillary action of the fluid in the wick and thereby induce condensation of the vapor phase in the pores of the wick. In a further aspect, the apparatus relates to a controlled environment within a sealed housing of an information storage device. In such an apparatus, a wick is mounted in the controlled environment, a portion of the wick being in contact with a storage medium. A liquid in the controlled environment is present in a quantity sufficient to maintain a determined quantity of fluid at the interface between the storage medium and an interactive element and to saturate the wick. A motor rotates the storage medium causing the vapor phase of the liquid to condense in the pores of the wick to maintain the determined quantity of fluid on the storage medium.
