In which areas are magnetic tapes are still used?
1. video-recording
2. audiotape
3. long time data storage
4. data backup
Why are magnetic tapes not a good idea if there are multiple read/write accesses?
1. they are not rewriteable
2. the magnetic layer wear out fast
3. high energy consumption
4. complicated reading procedure
