tape and disc storage are actually verry simmiliar. they both store information in the same way. the difference is disk storage uses a platter which is like an audio record. it contains a spiral of ferrite particles that can be positioned up and down or left and right. tape storage is very simmiliar to reel to reel audio. it contains the same ferrite particles suspended on a very simmiliar surface but the tape is very thin and long and on 2 reels. the reason why disks have replaced tapes is because of the time needed to write and read information. on a disk, the platter is spinning and a read/write head can swivel a matter of inches and read any place on that platter. if you want to read information on a tape, you have to first scroll to that point on the tape.

Tape and disk media store physical records differently. On tape, a physical record is written between interrecord gaps. On disk, a physical record is written in multiple units of a fixed number of bytes, which is determined by the hardware and operating system involved.This is the basic difference.
