The use of magnetic tape improved the performance of computers by giving them the ability to read and write data quickly and reliably.
Punched cards & magnetic tape
It is used for storing information which can be retrieved on a tape player or some computers.
Magnetic tape for computers was introduced in 1951 on the UNIVAC i, but was probably "invented" in 1948 or 1949 while Eckert and Mauchly were trying to think of ways to get data into and out of a computer at "electronic speeds" to avoid the bottleneck of then existing electromechanical equipment. Magnetic tape for audio goes back to the 1930's, although practical civilian applications had to wait for the end of WWII. (The Germans used magnetic tape during the war, while the Allies had only wire recorders.)
Magnetic tape is used to store music in old cassettes
A computer program magnetic case tape should be installed in the magnetic tape unit when it is not spinning.
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.
No difference - a cassette contains magnetic tape.
1940s to 1958: vacuum tube computers, primary I/O magnetic tape or punched cards.
Magnetic tape can be used in tape recorders and video tape recorders. Magnetic tape is also used by many companies for data storage. If the magnetic tape is stored improperly it can deteriorate.
Ghosts on Magnetic Tape was created in 2003-05.
Tape devices on computers could record and play magnetic tape. They are not so popular now, but would have been before more modern storage devices. Some can still be use for backups of data.
The largest capacity magnetic tape (as of the time of this answer) is 1 Terrabyte.
