Higher performance in smaller formats is a very good thing. But there is one drawback. As recorded wavelengths go down, the potential signal loss caused by small particles of debris goes up. Which means regular cleaning is more important than ever. That's why Canon introduces this digital video head cleaning cassette that will help you eliminate dramatic signal losses. Canon cleaning tape is made exclusively for Canon MiniDV camcorders. Specially formulated cleaning material gently removes debris from camcorders heads. Regular use of cleaning tape extends camcorders heads life.
