"Since the mid 1990s, all tray loading players have wells for the CD3."



Unless you're saying it wasn't standardised, in which case

"When Mini CDs were first introduced in the United States, they were 
initially marketed as CD3, in reference to their approximate size in 
inches; larger CDs were called CD5, despite the fact that both CD 
specifications are defined solely in terms of metric units."

The phrase "both CD specifications" seems to indicate that there's an 
official specification for the mini-CD standard.

In my area, for a bit under that price, I get a spindle of 100 DVD-R, 
DVD+R or 100 CDR.
So, if the mini CDs are the same price or higher than regular CDs, why 
bother?

I guess it wasn't Dr. Wikipedia, now where *did* I see that....?

Ah, yes, the article at http://en.wikipedia.org/wiki/Compact_Disc

I'm not the one looking for them.  I would guess if someone wanted that 
specific form factor for some reason, they'd spend the money for them.  
Perhaps someone with a mini CD audio player.

I guess it just seems somehow "wasteful" to me to use an entire 80 
minute disk to store one 2-minute track, that's all. You're probably 
right about there being no price advantage. Presumably "most people" 
want to buy a disk that holds the maximum possible amount of data (which 
is why mini-CD is so hard to find in the first place, and probably why 
they get made in smaller quantities and so cost more).

I was looking at the second paragraph, which states that they have varied 
in size.

That they did indeed vary in size doesn't mean there's no official 
standard size.

I don't think I said that there wasn't one (if I did, my mistake), just 
that they do vary in size.

Seems a silly thing to be arguing about, though. :)

Indeed I did.  Whoops.

Memory's the second thing to go.
