ABSTRACT:
An improved liner material for wiping debris from recording media to eliminate errors in the transmission of information with respect to the recording media. The liner material is a fibrous web which has fibrous surfaces and void volumes therein, the improvement being that the liner has at least one surface, with a fretting area of free vibratable fibers of at least 10% of the total surface, in contact with a surface of the recording media, and when vibrated against the recording media, and in contact with debris thereon, the free vibratable fibers impart energy to the debris causing the debris to move into the void volume of the liner, thus removing the debris from the recording media. The removal of debris from the recording media results in the error-free transfer of information from a recording transducer to and from a recording target media.
