Abstract

Systems and methods for prevention of condensation of ambient water vapor due to evaporation of frozen carbon dioxide particles used to clean data storage tapes. Various embodiments maintain conditions under which condensation cannot form in the ambient environment immediately surrounding a portion of a rigid surface on which the tape is maintained in thermodynamic contact and under tension (e.g., a metallic capstan around which the tape is wrapped).
