magnetic storage devices
How it works:
•A magnetic disk's medium contains iron particles, which can be polarized—given a magnetic charge—in one of two directions (north or south).
•Each particle's direction represents a 1 (on) or 0 (off), representing each bit of data that the CPU can recognize.
•A disk drive uses read/write heads containing electromagnets to create magnetic charges on the medium.
Diskettes:
•Diskette drives, also known as floppy disk drives, read and write to diskettes (called floppy disks or floppies).
•In disks the areas to save data are organized as a set of concentric circles called Tracks. Floppy disks have 80 tracks. The disks are further divided into pie-slice Sectors.
•300 rpm
•Diskettes size: 3.5-inch.
