Yes the magnetic media does allow you to delete existing data and save new ones (rewrite)
Magnetic
A magnetic tape is a secondary storage media used to access data in a sequential way
Yes, storage media can be damaged by magnetic and electric fields. Strong magnetic fields can disrupt the data stored on magnetic media such as hard drives and floppy disks. Electric fields can cause data corruption in electronic storage devices like solid-state drives and flash drives. It is important to keep storage media away from strong magnetic and electric fields to prevent damage.

An advantage of magnetic input media, such as magnetic tape or disks, is that they provide a cost-effective way to store large amounts of data. Magnetic media also offer fast access to stored information and are portable and easily exchangeable between systems.
Magnetic storage media are items like floppy and hard disk drives. They are based on magnetic transfer of data between the heads and the computer.
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.
Magnetic media refers to storage devices that use magnetic properties to record and retrieve data. Common examples include hard disk drives (HDDs), magnetic tapes, and floppy disks. These devices store data by magnetizing tiny particles on a surface, allowing information to be encoded and read by magnetic heads. Despite being largely replaced by solid-state drives, magnetic media remains relevant for certain applications due to its high capacity and cost-effectiveness.
No. Floppy disks are magnetic media that rely on magnetic polarization to write data to the disk much like a hard drive. Unlike CD media they can be erased by a strong magnet field that effectively scrambles the data tracks.
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
In a way, yes. The material that makes up the "disk" in a floppy is Mylar, a magnetic substance. Data is stored on the Mylar disk in the form of magnetic charges.
