What does it mean?

Most removable magnetic recording media had physical characteristics, typically in the form of a notch or recess built into the casing, that served as write protection. Blank media would come in a writeable state, then once you finished recording, you would snap off a little tab to render the media write protected. Commercial media, like music and video, would be sold in a write protected state. People would commonly use tape on the casings of write protected media to disable the write protection.
