How to erase the video recorded on a cassette tape.
To erase the video recorded on a cassette tape, you can simply record over it or use a bulk video tape eraser. First, ensure the write-protect tab on the cassette [FIG. 1] is set to the REC position. Then, rewind the tape to the beginning of the video that is to be erased.
WARNING: There is a risk of data loss. Once the video has been erased, it cannot be recovered.
NOTE: Sony does not manufacture bulk video tape erasers.
