why do they still make tray cd drives?

is there anybody who doesn't want a slot-load drive? I don't think the slot load mechanism would be much more expensive than tray. so why don't they just make only slot-load drives?

Because Slot load drives can't handle 8cm CDs.

I love slot load drives. Every CDROM I have ever owned has been a slot load drive.

Had one problem once, Samsung Yepp came with one of those little mini CDs.
I had to burn it to a full sized disc so I could load the drivers and software on my girl friends machine
since she only had a slot load drive.

>Is there anybody who doesn't want a slot-load drive?

Yes. I don't. I have a hard enough time getting the CD to the player without getting my finger prints all over it as it is. It looks harder to do with a slot-load. Holding on while it's grabbing looks tricky. I don't know how the drive does it, but it seems like they might grab it on its surface, which could potentially mar it.

What would you say are the advantages of slot-loading?

There was a time when CD drives commonly required a carrier that you put the CD in before you loaded the carrier into the player. When those without started to take over the market, there were people who would not buy drives that did not use a carrier. You needed a carrier for each disc, and the carriers where several dollars a piece.

There was a drive that had neither a motorized tray nor slot loading. Mitsumi was the first CDROM maker to sell a drive that cost under $200. (Probably they were the first maker to sell one under $300. At $200 I started thinking about buying one.) You pulled the whole player forward with your fingers, lifted the top cover, and laid the CD in, sort of like a record player. It actually isn't any harder or slower than a mechanized tray.

Historians will recall that CDROM drives for many years used one of three different interfaces (besides SCSI), none of which was the IDE interface.

I imagine the tray mechanism was a requirement of the Philips licensing. (Phiilips was the CD inventor.) Philips idea in licensing was to insure that everyone conforming to it would be compatible with everyone else. If you change one little thing, you have unforseen consequences. Slot load works OK, although possibly not conforming to the standard. 3" CD works OK, although possibly not conforming to the standard. But 3" CD and slot load don't work at the same time.

You don't really have to have a Philips license to make CD drives, I don't think. But you are supposed to conform to the license if you display that "disc" logo. I once read that Philips was attempting to crack down on people who display the logo but don't conform.

You would be surprised at the number of "normal consumers" who cant choose the right slit to shove a cd in and end up with a pile inside the case

ok, so it sounds like the only *good* reason is that they can't handle miniCDs. does ANYBODY use those???? anyway, I'm sure it wouldn't be too hard to make a slot-load that does take them. maybe have sort of 1 grabber for each size in the drive.

Isn't there a small risk of CD's getting scratched as they go in? Even if there's a protective typee thing it could still happen if the drive goes wrong. Trays are probably more difficult to break a CD with (I've never done it at least). Slot loaders are less likely to get broken tho, as if you forget to retract the try you could damage it. Maybe it's because people are used to trays, so they keep making them? Maybe trays are cheaper to make/easier to make. There could be many reasons, but I expect you'd get more slots if they were really the better option.

well,think of it this way, don't most cars have slot loading cd players (in fact they all do!)

The only reason they don't make them for the pc is because of the mini discs and the havoc they'd have if somebody shoved one in and it didn't work, only times that by all the stupid people in the world and you got a lot of problems...

My car's slot loading CD player is malfunctioning.. it doesn't take the disc sometimes, even if you push it in all the way. That's enough reason for me not to want a slot load drive on my PC.

On my old car, the CD player would not eject the CD properly. That's why I won't put a slot-load CD drive in my PC. At least on a tray-load drive, you have the little manual eject hole you can use if the tray won't come out on its own. If a CD gets stuck trying to eject from a slot-load drive, your pretty much screwed.

The tray in CD-based devices is a must, if you really care about things like mechanism quality, reading precision, jitter control, noise damping etc. There is a reason why home theater and profesional audio and video machines have trays. The clamping mechanism used in slot loaders cannot be guaranteed to keep the disc intact, and warping might occur in some extreme cases (prolonged use of the same CD, taken out and being put back in)

Slot loaders are also very sensitive to dust, and if dust particles get stuck in the right places, you'll scratch your CD every time you put it in. Read an audiophile magazine every once in a while, and see what kind of felings the people there have about this solution...

As for the mini-CD format being used... well, why not go for as much compatibility as possible? You ask if 8 cm CDs are ever needed - well, nowadays we rarely use the floppy, but most people like to have the drive present on their machines. And suppose you'll one day find a CD you desperately need to read - and oops, it's small, or Credit-card sized. What do you do?

I have slot loading DVD-Rom drives in each of the last 3 PCs I built. They have all been running for over a year and with heavy use. Never had ANY problem with any scratched CDs, CD explosions, etc.

If I were to have to use a mini disk (which I have NEVER encountered) I would read it from my tray-loading CD-RW drive. Not difficult, in this day and age, to have at least one tray-loader on at least one of your networked computers, it's all you could possibly need.

BTW, the slot-loading drives have a dust barrier built in to them. And no, it is not more difficult to handle the CDs and keep your fingerprints off.

I like efficiency, there are 50% less eject/load steps to take each time you use a CD, think about it.:)

You can use any type of mini-cd with a slot load player if you keep an adapter around. The one time in 10,000 that you need to use a mini-cd, pop it into the adapter and slide it in. IMO, the mini-cd issue is a non-issue. Not enough people use them, and if you come across one, you can easily read it if youre smart enough to keep the adapter around.

You'd be surprised at the number of technosapiens who do that while drunk, too.

Not me, really. I've NEVER done anything like that. ;)
