@nixCraft And you had to flip it over to access the other 5 MB… /s

No, you didn't. The reading heads were located on both sides. Such a disk was not very visible because it was inside a plastic box. The same disks were used for 5MB and 10MB, by the way. The difference lay in the disk reading/writing system.

@CatChucks @nixCraft I honestly did swither as to whether I actually needed to add the sarcasm mark (/s)… 😉

The other little known feature of these disks was that if you set the drive unit rotational speed to 33 rpm rather than 45, you could store an extra 1.5 MB per side… 😙

You know, many young ones cannot believe in that history… they might get the story directly…

I played with speed, too. 😁

Remember the fun times in the computer lab, when you go to load your program from the hard drive, but someone has discretely changed the knob from 33prm to 78rpm as a prank.

Sure. I had to lock the disks in a safe, but there were common ones :)

You've forgotten abut 78/45 rpm 🤣
