Laptop optical drives

[Tiburon1186]

Are these all standard? Well the normal ones (not the super thin ones or anything). I'm looking to replace the one I have on my laptop w a Blu Ray one (reusing the drive tray header from my laptop now). So basically is the form factor (not the connection [i know sata/ide etc]) the same for the majority of laptops so that I can swap it out and swap a new one in?

Thanks

Afaict there are two thicknesses and two interfaces but other than that they are basically standard.

I assume the thicknesses are normal sized and super thin?
