Video Head Cleaning

Whenever a video cassette is inserted into or ejected from your VCR the video head is automatically cleaned.This should mean that additional head cleaning should not be necessary.

However dirt accumulating on the head after a long period of time can cause the playback picture to become blurred or broken up. High quality video cassette tapes will not normally deposit dirt onto the video head, but old or damaged tapes might.
