ABSTRACT:
The cleaning tape comprises a substrate on which is overlaid a coating that provides a mechanical abrading surface to clean the elements in the tape path, such as the read/write heads. The coating has a high coefficient of friction to remove and retain the residues that have accumulated on the read/write heads. The coating is impregnated with or encloses a cleaning solvent that is controllably released by the mechanical movement of the cleaning tape over the read/write heads. The cleaning solvent can be isopropyl alcohol or other solvents that are encapsulated in some manner in the cleaning tape. As the solvent is released on to the read/write heads, it chemically loosens the debris which the abrasive coating can then mechanically remove from the read/write heads and also retain on the abrasive coating.
