Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the dominant modern format?LTO (Linear Tape-Open) with ongoing generations
2. What is the typical archival lifespan?30-50 years under optimal storage conditions
3. What is magnetic tape and how does it remember sounds and pictures?Magnetic tape is a long ribbon that stores information by changing tiny magnets on its surface. When a read/write head passes over it, the magnets are turned on or off to write sounds or pictures, and the same head reads them back later.
4. Why did people start using magnetic tape after World War II?After World II, companies like Ampex and IBM improved magnetic tape so it could record very clear music and later store computer data. This made tape a powerful tool for keeping big amounts of information.

Ferromagnetic Material: A material that can be magnetized, used as the recording medium on tape.
Sequential Access: Data must be read in order from the beginning of the tape.
Cold Storage: Data stored offline, typically for long-term archival and security.
Petabyte: A unit of digital information equal to 1,000 terabytes or 1 quadrillion bytes.
