Images on a videotape are stored using which method?

• A. Magic
• B. Magnetism
• C. Paper
• D. Computer memory

Answer: (B)

Magnetic recording. A videotape is coated with magnetic particles, and the video signal records as tiny magnetization patterns on the tape as it moves past the recording head. When played back, the read head detects those magnetic variations and converts them back into the electrical signals that reproduce the image. This is magnetic storage, not something magical, not paper, and not electronic computer memory stored on chips.
