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.
Magnetic drums

There are primarily two types of magnetic tapes: analog tapes and digital tapes. Analog tapes store information using varying magnetic fields and were commonly used for audio recording. Digital tapes store data in binary form and are used for data backup and archival purposes.
Floppy disks use magnetic disk to store the data.
Magnetic tape is a data storage medium that stores data magnetically on a thin plastic strip coated with a magnetizable material. It is commonly used for backup and archiving purposes due to its high capacity and relatively low cost. Data is written to and read from the tape using a magnetic recording head.
