Saving a recording
Video tapes have a safety tab to protect against accidental recording. To
prevent accidental erasure of a recording, break off the safety tab with a
screwdriver or other tool. A tape with its safety tab removed ejects if
you try to record on it.
To record on a tape with its safety tab removed, cover the tab hole with
adhesive tape.
