(old timers alert!).
I was reminded of these in a conversation with a person who worked for Tandy in Fort Worth during their personal computer days.
A flippy disk was recorded on both sides, but was designed to be read in a "normal" (for the time) single side disk drive. It had two sets of write protect notches, and you'd physically flip it over to read the other side.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them.
I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

"A flippy disk was recorded on both sides, but was designed to be read in a "normal" (for the time) single side disk drive. It had two sets of write protect notches, and you'd physically flip it over to read the other side."
This was also a common practice with Commodore C-64 and C-128 computers when used with the 1541 single-sided floppy drive. It was considered to be a shaky practice, as flipping the disk caused it to be rotated in the "wrong" driection, which would occasionally result in damage to the magnetic coating on the disk. The advent of the double-sided 1571 and 1581 (3-1/2 inch) drives gradually brought this practice to halt.
