Magnetic tape is sequential by it's extremely nature to read a record you must start at the beginning of the tape and sequentially read every record until you get to the one you want. With disks, obviously random access is possible. It is the same as the difference between audio compact disc and audio cassette. With audio tape you have to begin at the beginning and run the tape forward until you get to the song you want to hear. With compact disc you are able to play the songs in random order or go directly to the track you want to hear.
