Abstract

PURPOSE:To perform, in an apparatus for a magnetic tape, noncontact stabilized running of a tape and to improve a degree of vacuum within a vacuum chamber, by arranging bypass evacuation passages in a sealing portion to evacuate gas flowing in from outside and blowing gas against the tape. CONSTITUTION:To a lower block 12 of a seal are provided three pairs of evacuation passages 15 for bypass evacuation in a symmetrical pattern with regard to a running direction of the tape. Thus gas in a tape passage 10 can be evacuated through the evacuation passages 15 and evacuation holes 16 by a gas suction source 5. Further to upper and lower walls of the tape passage 10 are arranged gas supply holes 17 for discharging gas from a gas supply source 18 to form a static pressure gas bearing in the form of oppositely supplied gas. Accordingly, running position of the tape 4 can be retained at a center of the tape passage 10 to secure noncontact stabilized running of the tape 4 and in addition to improve a degree of vacuum.
