homemade double sided cds. Possible? Good Idea?

[ViperXT]

Since most movies take up 2 cds in vcd format it would make since to have them close right? Could you take 2 cds and glue them two each other with the label sides in? If they were glued straight I think it would work. or is the 'disc" now too thick for the player or does it matter? Any feedback would be nice.

[Riot_Inc]

that's what i was thinking about the other day, how come dvd's can be two sided, but cd-r's can't. try it, and hopefully you'll have back up money in case you fu.ck up your dvd or cd player... and if it works, i might give it a shot

[wcb4]

If you have a "CD Stomper" to apply your labels, then you already have a way to make sure they line up properly. Let us all know if it works. The only problem then, however, is which side is side 1 ?

[ViperXT]

yes i do have a cd stomper! I think I could number them on the inner ring of the disc. I dont know if i should try this or not! anyone else ever try it?

[Vejita-sama]

Do you have an old or extra CD-ROm somewhere to test this guy in instead of your DVD-ROM? It'll be twice as think so I'm not even sure the door will close. Plus I don't think any CD-ROM or DVD-Player will read the other side automatically, so you'll need to flip the disc. If you have to open the tray, take out the disc and flip it; you might as well just have put in the 2nd disc

But good luck, and keep us posted it sounds interesting...

[ViperXT]

I will try it on an old 4x cd-rom i have sometime soon. this should be good

[ViperXT]

also does anyone know where i can buy jewelcases with capacity for 2 cds?

[patrickm]

i don't know about this idea. first off, you have the moment of inertia problem. you're not only doubling the weight of the disc and stressing the motor, but changing the whole dynamics of the system.

the other problem is thermal. when discs heat up, they don't necessarily expand at the same rate as glue, so be careful with what you stick these together with. a dab of superglue along the inner edge might not hurt (but NOT on the reflective surface). but delamination is still an issue.

[suspect]

i don't think this is gonna work. I've accidently put a dvd on top of another one in my dvd player before, and it does spin up, however it was making noises and couldnt read the cd that it should have been able to if this works (the one on the bottom). Of course the cds werent glued together. . . I think buying 2cd jewel cases is a better solution.

[JJamez]

I don't know if this will work or not, but I'm interested to hear. I think it depends on how much stress will be put on the glue - I don't know that you'd be stressing the motor much, as once it is spinning the motor shouldn't have to work too hard.

Once experience I'll relay here - have any of you had a CD 'blow up' in the drive? I was using a Win98 CD that had a hairline crack in it (it got under my ass somehow and I sat on it

So basically, aim your drive AWAY from you AND your face whilst trying your 'double-sided' cds...

@JJamez

Very (sorry!) amusing story. I wonder if it has to do with the fact that these lasers can produce quite a bit of heat, especially if the head doesn't move and stays fixed on one point?

@all

So apart from the warnings that JJamez told you, don't forget the security goggles, the hard hat, fire-extinguisher, First-aid kit... hmmm, anything else I forgot?

I don't have much to add except that its a BAD idea. Your probably end of breaking whatever drive you use. I think this is one of those "kids don't try this at home" situations.

[NightWing]

Deffently would not recomend it for the following:

(1) The disk would be too thick.
(2) The layer you would glue hold the data just under a lacquered layer.
(3) The stress would be too greate on the joint and drive.
(4) Would take special glue to hold.
(5) You still need to eject and flip the disk over.

CompUSA has a new CD case. If the package is correct it stores 4 cd in the space of a std CD case size. Also they are stocking CD "Cake Box" style in sizes from 5 CD to 50 CD storage.

This is going to be like an accident you see as it's developing. You know something bad is going to happen, but you do nothing to stop it just because it's interesting to see what's going to happen.

[JJamez]

Here's a pic of what I do with my 3 CD SVCD rips.



Just carefully cut out the middle with an exacto knife and 3 CD's fit comfortably.

[orbit7]

This is definitely not work due to the density of the disk. the disk will jam on as you remove as it will get stuck on the top plastic assembly upon eject. Ive noticed this from putting laminate on some cdrs to verify how thick a cdr can be for testing purposes. after approx 1.8 mm the cdr becomes to thick and starts to jam.
obviously this will depend on the player that you use

[Stansell]

I once saw a commercial CD single (long ago) that was like this, but I think it was a bad idea.

Even though there are double-sided DVD's, if you look at them you'll notice they are no thicker than a CD or DVD.

Also, if in the future you were to buy a multi-disk changer, you would have to flip the CD instead of loading them in the changer.

My advice - don't do it.

[Graham Meredith]

Sounds like an interesting idea, but whatever you do, DO NOT USE SUPERGLUE !!! Use any other glue like epoxy 2 part glue or plastic glue, but not "superglue" or any of the instant glues. The cyanocrylate in the glue corrodes metals - especially circuit board tracks and electronic components. The glue does not even have to be on the component to corrode it, it just has to be in its vicinity eg. a glued CDR in a DVD player. It emits fumes for weeks, and these will corrode anything metal in their vicinity - especially closed in like a player. I found this out the hard way. I had a radio controlled model car, and a plastic bracket in the transmitter broke, so I glued it with superglue. A day later I used it, and for no apparent reason, the car went crazy and wrote itself off in a gutter (sob!)
When I opened the transmitter up, all the circuit board tracks in the vicinity of the superglue repair were corroded and covered with a white coating, all the chips were corroded in their sockets. Bastards!

I would not advise it.


the counter weight might scratch the CD>

[vitualis]

I think JJamez described very well why this is a bad idea. Irregardless of how strong your glue is, there is a good chance that you will eventually delaminate your two CDs...

The best outcome if this happens will simply be loss of data on both discs.

The worse outcome is that the discs catastrophically breaks apart and damages your drive/PC/you.

Remember, modern CD drives can spin anywhere up to 50x single speed. At this rotation, there are some very high forces at play.

I think the idea of a double sided CD is great, but glueing them, not good. I wonder if anyone sells double sided. Some DVD's are that way so why not CD's.

My DVD (SONY CX850) play is a juke box that will flip the CD so I could double my collection 300 + 300 =600 WoW.

They are available but in my opinion overpriced. I take two single cases and glue them together back to back. You can also take a coaster you may have burned and place it in between the two cases. This fills the small gap between the cases great. Finally a use for coasters. And superglue works great for this.

[Greg12]

I don't see why u r doing this.


You have to get up to change cds, you have to get up to flip cd's.

LOLOLOLOLOLOL.....

The perfect answer. Classic "forest and the trees" scenario.
