Disc Mount - Store and Display CDs on Metal Surfaces




About: Inventing new and unique products for people, robots (if they ask nicely), and a few plants.

A disc mount is a small, magnetic holder for a CD to solve an access, storage, destruction problem we ran into time and again in our gaming area. Now we can store our discs on nearly any metal surface and rearrange as needed. The convenience and flexibility has resolved the problem. Learn more on our Disc Mount Project Page. In our case, we modified the back of a poster with tin to give us a fun display to store our discs. I show you how to do this poster frame mod in the instructable, Poster Magnet Board.

This instructable shows you how to create a disc mount in less than 10 seconds and how to use it.

Learn more details on the project page.
See more pictures in our Disc Mount gallery.

Here's a video on using Disc Mounts:

Step 1: Get Parts and Materials

We designed the disc mount to securely attach to a poster, with an acrylic face up to 3/32 in. thick, upside down, holding a CD. (Hey, you never know how people might attach their CDs, right?) So, the strength of these are over-kill for attaching directly to bare metal, but works great for metal covered with materials such as laminate, fabric, vinyl, acrylic, etc. To build a disc mount you will need the following:

  • 1, foam cd hub (0.52 in. diameter x 0.375 in. thick)
  • 1, nylon washer (0.85 in. diameter x 0.395 in. diameter hole x 0.062 in. thick)
  • 1, neodymium magnet (Ni-Cu-Ni plated, 0.375 in. diameter x 0.062 in. thick)
  • 1, white vinyl sticker (0.75 in. diameter)

Be aware that safety is your responsibility. Please read our Safety Warning and Disclaimer before you start.

Step 2: Stick Foam Hub to Washer

Foam CD hubs come with one side that is sticky. Place the sticky side of the foam hub onto the center of the washer. It doesn't have to be perfectly in the center, just close. To make sure the adhesive sticks, apply firm pressure between the foam hub and washer for 2 seconds. Do not flatten/crush the foam hub.

Step 3: Place Magnet Into Washer

Flip over the hub-washer assembly. Place the magnet into the hole in the back of washer-hub assembly. To make sure the adhesive sticks, apply firm pressure between the magnet and foam hub for 2 seconds. Do not flatten/crush the foam hub.

Step 4: Cover Magnet With Sticker

Place the sticky side of the vinyl sticker in the center of the washer to cover the magnet. This doesn't have to be perfectly in the center, just close. To make sure the adhesive sticks to the washer, apply firm pressure to the vinyl sticker in a circular patten.

Congratulations! In less than 10 seconds you have built a disc mount.

Step 5: How to Use - Placing and Removing

Your disc mount can stick to any metal surface that contains a significant amount of iron (galvanized steel sheet, for instance). Examples of metals that will not stick are:

  • aluminum
  • copper
  • nickel
  • titanium
  • most grades of stainless steel
  • brass

Place your disc mount on a metal surface by holding onto the outer edge of the washer while bringing it very close to the surface. Release. To remove the disc mount, grab onto the outer edge of the washer and rock it forward from one edge. (You may need fingernails to get leverage.)

Do not remove the mount by pulling on the foam hub.

Step 6: How to Use - Mounting a Disc

Align the hole on the disc with the foam hub on the disc mount. Gently push the disc so the foam hub passes through the hole and rests against the washer.

Step 7: How to Use - Removing a Disc

Using 1 hand, rest your thumb on the edge of the disc and place your index finger on the foam hub. While holding the foam hub in place, pull your thumb towards you while dragging the disc off the foam hub.

Step 8: Display

OK, now where to mount those discs? I like using posters that have been modified with a tin backing. I show you how to do that in the instructable, Poster Magnet Board. Otherwise, attach them to common metallic items around the house or build your own cool display. Lots of possibilities...have fun!

    It won't affect it at all. The data layer is behind a layer of plastic, so unless you scratch it badly it won't affect the disc. This was one of the major selling points of cd's when they came out.
    Infact you can safely wash a cd in with the dishes and still use it, once dry that is ;)

    I agree. Great idea, just worried about CDs being exposed to the elements rather than in a case or holder of some sort.

    Good idea, but for those of us without metal walls I suggest getting thin metal strips and make a design on the wall !! Maybe in a tic tac toe design. Paint the strips to match the room - or not...
    Have fun with it!

    i like the general dea about this. but i think ill do this with my dads old vinyls!! or make a floor with vinyls on it


    10 years ago on Introduction

    This is such a cool idea! We have a spare bedroom converted to a "video game room" and this would just rock in there! Great ible!

    Ok. Before I say anything else,
    this being said....It really does look great and probably works well.
    The only problem is i have a bunch of *4.7gig* CD's and
    Magnets (MAY!!!! That is MAY!!!) destroy CD's.
    Other than that, great instructable and if there just for decoration. even better :D

    Magnets have absolutely affect on cds or dvds (your 4.7gig disks) because cds run on optical, but other things like floppy disks, vhs tapes and most hard drives could be damaged by direct magnetic contact. (with hard drives it takes more magnetic power than you can accidentally expose it to, i've tried with a very powerful magnet to erase the data, but it was still intact, but its never a good idea to put magnets near hard drives.)

    Why would magnets have any effect on cd's or DVD's? In the days of magnetic recording this may have been a viable comment (MAGNETS+EXPENSIVE CASSETTE TAPE=BAD TIME) but now in the future we actually burn the CD literally. The burner in your computer burns tiny bits of ink in the CD and it represents the 1's and 0's. ANYWAY, back from my high horse I agree it is a great instructable and it was made better by the fact I got to rant at you for next to no reason. Brilliant Instructable, really presentable and thank you darkmuskrat for being that person who I ranted at today. I remind myself of Doctor Cox (In his head: Must rub something in someone's face... Aloud: So how's that coma going for ya? In his head again: Much better!). To sum up it looks brilliant.

    Ok, like I said it was a big "MAY damage them". I just say this because i had a stack of cd's i knew worked in a box with a bunch of insanely strong earth magnets and after 2 weeks they didnt work (all 50 of them)....ill look into it, but i still say; "this instructable is awesome!


    As stanoster mentioned, magnets will not harm CDs, DVDs, CD-RWs, DVD-RWs, etc. These discs are made of plastic with the data encoded as bumps molded on the plastic, or (in the case of RW's) opaque dots in a clear dye layer burned in by a laser. Both of which are not affected by magnetic fields. If you are curious, HowStuffWorks has some good background on this:

    Construction of CD
    How CD Burners work
    How CD-RWs Work

    No worries...we've been storing all of our games this way for nearly a year.


    Excellent question. We've been using this system for over 2 years and haven't had any problems with dust on the CDs. Oh, and we do have lots of dust in our house (we live in the "sticks").

    We mount our CDs on posters with metal backing, or metal straps on the wall. So dust doesn't have much of anything to settle on. I imagine if you mounted them on a horizontal surface, like a table top (I have no idea why), dust could be an issue. But, if you plan to mount them vertically...no worries.


    Thanks for replying. We have lots of dust in our house too and it was good to hear we are not the only ones... :). I can't wait to try this idea. Two teenagers with playstations, music CDs etc can drive a person insane with the constant picking up and putting away of CDs so they don't get wrecked and the equipment doesn't get wrecked from the dust. I'm still trying to work out why I bother!


    You pretty much described the situation that caused me to create the Disc Mount (except you need to replace "Playstation" with "Wii"). We lost many CDs to scratches and cracks...expensive.

    Having the disc mount systems right next to the console, computer, and stereo worked for us. Kids have picked up the habit to pop the CDs on/off without thinking. Now if I could just figure something out for socks... ;)
