What is the difference between tape, hard drive, mini-DVD, and memory stick camcorders?
Tape is a linear recording media, while mini-DVD hard drives, and memory stick are non-linear. This means that in order to view a certain portion of your previously recorded material, you have to fast-forward or rewind your tape to do so, while with mini-DVD, hard drive and memory stick, you can skip directly to the portion that you want just like a regular DVD with chapters.
