Have you looked at the blu-ray specifications? No you havent because if you had you would see that Blu-ray has Mandatory hard coating layer on the disc to protect it from wear and tear.
That hard coating layer is mandatory, because the disc would otherwise require a cartridge. The data layer is so close to the surface that the hard coating absolutely has to be there (that's what mandatory means). HD DVD discs on the other hand do not require hard coating... at all, and can still take more damage than Blu-Ray discs due to the fact that the data layer is located as in a regular DVD disc. That is why HD DVD discs could have the same hard coating as Blu Ray discs have, but there's no need. Companies can save money and not do any hard coating on the discs, whereas on Blu Ray they have to do it in every case... or use a cartridge.

Can you provide a link that shows how much it costs to make both of them?
That depends entirely on the company making the discs and how they're making them. HD DVD's do not require hard coating and are similar to regular DVDs, that's basically what makes them cheaper to make. I don't think
any company would give out that kind of information what you're requesting...
