Its called a floppy disk.
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.
Magnetic Storage
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.

Jump or flash drives store data in a solid state. This is different that a magnetic drives that store information in a different manner.
True.
We mostly store data by saving it. Binary information - the parts of the memory either take an electrical (or magnetic) charge, or they don't. The computer interprets this as data.

Floppy disks use magnetic disk to store the data.
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
Magnetic forces are not necessarily bad for computers, as mechanical hard disks use them to store information. However, you shouldn't place any magnetic objects near them as it will ruin your data that's store on those kinds of disks.
