Write Protecting Diskettes
Microcomputers provide built-in safeguards to make sure you do not
accidentally delete data. One of these safeguards is the mechanical
ability to 'write protect' diskettes. When a diskette is write protected
you cannot delete files from it or add files to it. Only diskettes that are
unprotected can be changed.
The system diskette is usually a write protected diskette. This is because
you don't want to delete any system files by accident. Program diskettes
are also frequently write protected for the same reason. Data diskettes
are not protected unless you wish to use them to look up information
only.

sturdy plastic jacket. Notice these parts:

During use, the diskette spins inside the jacket. The metal protective
covering moves aside and the diskette drive's read/write head makes
contact with the magnetic surface of the diskette through the head
window.
