Disk Polishing Goes Open Source
Optical media is great β itβs pretty high density, relatively durable, and decently long-lasting if

well cared for. If not well cared for, well, itβs only relatively durable, and weβve probably all picked up a second-hand disk thatβs too scratched to use. The X-Box 360 is notorious for causing circular damage, and while decent disk cleaners were easy to get in the 90s, weβre not sure how far we trust whatβs on offer at retailers today. Hence [Dennis], aka [RetroGameRevival]βs RGR ezBuff polishing machine, which does exactly what it says on the tin: buffs disks to a polish, easily.
Weβd say the whole thing is 3D printed, but of course you still need a motor and controller β if you had to turn a crank, that would just be a Buff polishing machine, no ez β and weβve yet to see a printer poop out polishing compound. If you build it, keep in mind that youβre taking the top layer of material off the disk to polish scratches away, so donβt overdo it. Itβs entirely possible to ruin a disk beyond repair with too-aggressive buffing; itβs also possible for disks to be scratched too deeply to save. Polishing canβt save genuine disk rot, though in our experience youβre more likely to find scratched disks than rotten ones. Still, [Dennis]βs birthday gift to the community β it was apparently released on his birthday β should keep more than a few disks out of the trash.
With Sony getting out of the disk game, physical media is becoming more precious than ever, so itβs good to see what looks like a quality polishing option for those of us who either never had a polisher or didnβt save theirs. If you really want your disks to last, maybe we should bring back CD caddies.
