this is a backup method typically used in server/client enviroments. at the peak of usage, it was far more expensive to buy a new hard drive for backup purposes, and would take multiple floppy disks to backup a network (Not to mention a ton of time) Magnetic tape storage offers relatively quick back up speed.
Before the advent of compact disk technology, magnetic tape reels held text, visual, audio, and video information. If you're old enough to remember, the VHS and cassette tape were the biggest uses of magnetic tape in entertainment use.
Magnetic tape is used to store music in old cassettes
Bulk data storage
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.
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
A disk drive is all three, depending on the situation. It is an input device when it provides stored data to an application. It is an output device when it receives data from an application. It is a storage system when it saves the data for future use.
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.
Tape drive and hard disk drive
You would use magnetic tape for recording music or other audio. Many industries in the audio recording industry use it. Magnetic tape can be used to put pictures on the refrigerator. It can also be used to put memos up in an office.
the magnetic storage devices, use magnetic property of the materials to save data in bits.
The petroleum industry used magnetic tape in geophysical exploration equipment
Nope. Flash drives don't use magnetic storage.
UNIVAC I
No, tape drives use magnetic means for storing and reading data. Any kind of Compact media, (CDs, DVDs, Blu Ray, etc.) on the other hand, use lasers to read and write data. (Verify that part, someone.)
The use of magnetic tape improved the performance of computers by giving them the ability to read and write data quickly and reliably.
