Is it safe to use those mini-sized discs (not a regular size) in a 15" MacBook Pro's disc drive slot from 2008? I know they work fine in the old fashion tray drive, but what about those slot ones that suck in to insert and eject out?
Thank you in advance. :)

Definitely not. The mechanism can't grab it properly.

You maybe can force it if you cut a hole in a regular coaster and glue it in. For Pete's sake, wait till the glue dries though, and sand it smooth.

It is not safe to use the mini-discs or any other sub-standard-sized
discs in any slot-loading drive. Thus the answer is "not only no, but
Hell No!" This is one of the two major negatives, in my opinion, of
Apple's obsession with slot-loaders on all Macs other than the
MacPro...the other is that slot-loaders are slower than tray-loaders.
Their sole advantage is that they are more compact, providing for a
smaller form-factor in the computer case. That doesn't mean that I
don't buy or own Macs with slot-loaders, I just augment them with
external tray-loading units (besides, having two optical drives
provides some benefits when it comes to making backups).

1: Faster and, at least in my experience, less error prone. The
slot-loaders in both my MacBook and iMac pitched about 2% coasters at
6x and 8x, but my tray-loading externals run well under 1% at 16x.
2: Our son and our daughter have camcorders that record to mini-DVDs. I
argued against the cameras when they purchased them about 6-7 years
ago, but they felt the price at the time was too good to pass up. Plus,
I'm the "video guy" in the family, so I'm the one who ends up producing
the home videos from the footage they provide.
Additionally, some computer games that our son was fond of, such as Tom
Clancy's "Politika", came on mini-DVD and he had a good-sized
collection.

Mini-disks in a slotloader are a no-no, as had been said.
However there's another problem. I have received CDs that have a
commmercial lable with self adhesive lable on them. If you use a slot
loader in a CPU (e.g. an iMac or lap-top) which gets hot, the heat
causes the CD and lable to expand at deffernt rates. The result is that
the CD refuses to play after a time in the machine. With music CDs the
sound deteriorates first.
I now use printable CDs for audio, when I want a lable.
Thank goodnes I kept my old Formac tray loading CD-R/RW, DVD-R/RW!!!

I have a few of these mini disks hanging around, they often come with drivers on for monitors, mostly the sort of thing PCs but not Macs ever really need.

Agreed...I still have and use my old Sony miniDV camcorder, but my wife
much prefers our Canon that records to SSD. In any case, the merits of
tape vs. mass-storage cameras isn't really germane to the discussion of
slot-loading optical drives (unless the mass-storage device uses
miniDVDs).

Yeah, those cheap labels suck. :( What about marker writings on the discs? Are those safe after they dry up?

Nope.
When I bought my SO a MBA, I also bought the Apple external drive. Sleek. But it would not work on my Mac (the MBA outputs over spec on power to the USB port).
I returned the Apple drive and bought an ASUS drive instead - which was also cheaper and thinner.
It has two USB connectors on the cable so that it can draw adequate power from the host. On the MBA I connect only one connection (there's adequate current available on it) and on other computers I connect both.
And, of course, it accepts the smaller disks and "card" format CDs in it's slide out tray.

The standard sizes are 12 and 8 cm. Apple do not meet the standard with the slot loader.
OTOH, nor do most automobile CD players.

I receive some marketing and RFP/proposal materials on mini and "business card" format CD's. Less now than a few years ago but as recently as this past summer. I bought a tray loader for my SO's MBA (other post).

Not every printer can print to a printable disc. Avery sells film labels especially for DVDs.

That's not the reason.
The reason that the Apple external SuperDrive doesn't work on anything
other than a MacBook Air (or a Mac Mini without internal optical drive)
is that the device driver only allows it to be used on a Mac model which
Apple supplied without an internal optical drive. The firmware on the
bridge board in the drive enclosure can apparently be hacked to get
around this restriction (presumably by appearing to be a generic drive),
after which it works fine with recent Mac models.
All Macs since about mid 2007 are able to supply more than 500 mA via
their USB ports, for devices which comply with the USB battery charging
specification (which allows the computer to supply up to 900 mA while
communicating at USB 2.0 high speed, if I remember the number right off
the top of my head).
These Mac models also recognise certain Apple peripherals (which are not
battery powered) and supply more current to them. This may include the
Superdrive (I haven't checked) but one example I know is the Apple
aluminium USB keyboard: the computer can supply up to 1100 mA to the
keyboard, allowing the keyboard to supply more than 100 mA to a device
connected to one of the USB ports on the keyboard (e.g. allowing an
iPhone, iPad or iPod to be charged while plugged into the keyboard).

The basic reason is the USB power level. The rest is implementation detail.

Umm, I used these non-printable Avery disc labels before many years ago. They did not stick well even after pressuring onto the discs for days. :(

no, the power level has nothing to do with it. the only reason is the

The _reason_ is power. The _implementation_ uses the custom chip to control which devices the drive will work on.
It is all about the power available on standard USB which is not sufficient for Apple's external DVD drive. Apple's implementation is by configuration's known to supply enough power (MacBook Air for example).
My ASUS external drive REQUIRES two USB females to operate to get required current. On the MBA it works with one only - because the MBA supplies enough current on that port - over compliance v. the USB spec.
Apple implement so that only specific h/w combos can work. That's why I returned the drive. I'd rather have the less sexy ASUS that works on any PC/laptop than the Apple drive that is constrained.
Apple could have simply supplied an additional Y cable with 2 USB males instead of unduly restricting use of their product through firmware. Or make the "Y" on the basic cable like ASUS did. Inelegant perhaps but more versatile.

nope.
the drive will not work with additional power, but will work when the
bridge chip is replaced, even on machines with limited power. the
custom chip looks for specific hardware and will only function if it
finds it.

Perhaps and I would venture that it draws current slightly over USB spec maximum laptops such as the MBA provide more current.
Case in point: my ASUS DVD works on the MBA with only one of its males plugged in to it. But on the iMac it _will not work_ unless both are plugged in so that it gets adequate current. Likewise on a PC or on a hub with its own PS.
So, I'm not wrong and neither are you right. It is one of those things in a grey zone and Apple have provided for more _current_ on the MBA than the USB spec requires.

there's nothing grey about it. the person who authored that link
*proved* the issue is a custom bridge chip. when it's replaced with a
generic bridge chip, the drive will work where it otherwise did not,
and that's even the same host. changing the chip does not change how
much power the host can source.
