How do weird shaped cds work?

[wiredspider]

I was talking about these ealier today, and I said they work by just reading the inner most circle of the cd, someone said it had something to do with the mbr table. Anyone really know how they work?

EDIT: Just realize how screwed up I made this question sound. I was trying to say that the cdrom would read the inner circle(silmilar to the shape of a mini CDR) of whatever the weird shape was, square, star, bubbly, jagged, or whatever

Someone must know!

Huh? Your cdrom/player just reads the TOC (table of contents). It knows how far the last track goes and doesn't go beyond it.

Well...how do regular CD's work?

It reads the TOC. Data and Audio CD's do that.

And what is a "regular" CD anyways? What "color" book are you talking about?

When the person said reading the MBR table, they meant the entire cd has data, like if it was a star shaped cd, it would store data at the points also.
