Well, I guess that you should clarify which kind of data recovery.

Nobody's know which will be the sure ways to recover a scratched CD or DVD?

A lot of people know how to do that, which is almost, but not quite, UNlike data recovery.
More often than not it is just a "mechanical" accurate polishing/smoothing of the scratches (there are machines for it), see this (including the Vodka trick wink )

And this definitley is NOT data recovery, it is hardware recovery.

I have used software for recovering deleted or formatted data but doesn't know any thing about hardware recovery like from scrrached dvd. There are companies which provide these services but they charge lot of money for that. What process they use can i learn also?

"Many electronics stores have a 'CD/DVD repair kit'. It works by sanding or polishing the DVD with a very fine grit material. It will actually remove some of the plastic on the DVD to return it to a readable state. It will not work on deep scratches. Once you have polished the DVD, put a protective cover on it so that if it gets scratched again, the cover can simply and easily be replaced."

Well, the actual companies charging money do something slightly different, substantially they put the CD/DVD on a lathe (in the sense of a rotating support) and sand/polish the media, removing - if needed - a substantial part of the thickness of the plastic, thus being able to remove even deeper scratches (though the same can be made by hand, with a LOT of patience) and re-polish perfectly the surface.
The "high end" machines look like these (examples)

http//www.discchek.com/

There are "cheap" manual (and motorised) versions too, example
http//www.digitalinnovations.com/disc-cleaning-repair/
http//www.jfjdiscrepair.com/

Of course the results with these latter, just like with manual polishing, depends much more from the capabilities of the operator.

What most people tends to ignore is that radial scratches/marks do not affect normally the reading, whilst even tiny scratches going parallel to the grooves may interfere with proper reading, if you prefer a CD/DVD "re-surfaced" with radial tools like the SkipDr may look much worse than before (and much, much worse than a new media) but still the laser has no issue in reading one, whilst media re-surfaced with a professional machine are normally indistinguishable from new media.
