プアウトの改善を行ってきた。Conventional technology In recent years, as video decks and video tapes have become more densely recorded, the recording and playback heads and running systems have also been improved. This can result in missing materials adhering to the head or travel system posts, or scratches on the head. These problems cause clogging and dropouts. Therefore, if clogging or dropout occurs, A, O3, γ-Fe2O3
Clogging and dropouts have been improved by cleaning scratches and foreign matter adhering to recording and reproducing heads using cleaning tapes having a resin layer containing an abrasive such as ゜Cry.
