Magnetic tape backup of your data is done with a magnetic tape data storage system. You can use digital recording to store your digital data on the magnetic tape as a backup.
A magnetic storage device is a device that uses a magnetic head to read and write data to and from a magnetizable medium. The medium can be as basic as a plastic tape that is coated with fine particles of a metal, such as is found in audio recording and tape storage devices.

In the previous lesson the punched card was discovered as one of the common forms of data recording media used for input and output. In this lesson the following recording media are discussed: printed output, diskette, paper tape, magnetic tape, cassette tape, and magnetic ink characters.
Backup tape storage works by recording the data that you write on the magnetic tape in digital format. This is then physically stored until you require to restore, where the process is reversed.
The principle of magnetic recording and reproduction involves encoding information onto a magnetic medium using changing magnetic fields. When recording, information is stored as magnetic patterns on the medium. To reproduce the information, a magnetic head reads the patterns and converts them into electrical signals for playback. The sketches would show the process of writing and reading magnetic data on a medium using a magnetic head.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drive.
Those are 2 completely different terms. MP3 refers to a file format for storing compressed audio, and data disc refers to a method of recording information onto a CD Rom in such a format such as computers and computer game systems can read data from them. Data disca can contain MP3 files though.
Data are the raw facts or figures which are processed to get the information.
The data written onto compact discs is in a digital format. It may not have originally been written in a digital format, but will be converted to digital in order to write it to a compact disc. Some music/audio compact discs show whether the data was digital or analogue at each stage of: * original recording * mixing * recording to CD by showing a three letter code where A indicates analogue and D digital. ADD would indicate an original analogue recording with a digital mixing and then the digital compact disc recording.
