Abstract
Cleaning apparatus for removing foreign material from the front or oxide-covered surface of a magnetic recording tape. A sharp edged blade is mounted near a pad of open-cell reticulated foam material, and in close proximity to the front surface of a magnetic tape. A source of negative pressure is coupled to the region of the blade and cell and when actuated serves to draw the tape against the blade and foam material. Foreign material removed from the surface of the tape is embedded in the foam pad, and collected upon the blade. Air flow effected by the negative pressure area serves to transport some of the contaminants away from the region about the blade and foam pad.
