Really...a question about floppy disks. Have me gone back to the late 80's?
The answer is "read/write" and "write protection". Both terms were used.
History lesson for you:
The disk had a notch that if you covered it the drive was not able to write to the disk.
The actual disk that was inside of the floppy was actually writable on either side. But because there was only a notch one side of the floppy, if you put it in upside down it could not write to the back of the disk. So we would take scissors and cut a notch on the other side of the floppy. then you could put it in upside down and use the back side of the disk also. Called them "flippy" disk.
Originally the floppy disk was 8 1/7 inches in size. They figured out how to pack the information tighter and were able to reduce them 5 1/4 inch in size while holding twice the data. Then they developed the plastic 3 1/2 inch disk held more data yet. they had a plastic tab that you slide over a hole to make them unwriteable rather then a notch.
Interesting, the 3 1/2 floppies where the same dimensions as the computer disk used on the original Star Trek series before any size floppy had been invented.
The CD, DVD and BluRay disk are all the same size as a 5 1/4 inch floppy because computer cases were designed to hold drives of that size. So they designed the CD to be the same size so it would fit existing computer cases.
