Title: Do Blu-Ray readers offer superior reading and error correction?
Post by: BFG on 2012-12-21 15:46:43
As mentioned in another thread, I'm having some trouble ripping a few of my older, lower-quality CDs.  One person suggested borrowing a new reader.

This got me to thinking: would a Blu-Ray reader offer superior reading and error correction on older (or more heavily damaged) CDs?  It would make sense to me that they would due to the shorter wavelength of the laser, but I'm no physicist.

I believe that the dBpoweramp website has a ranking of drives according to quality of rips. You might look there.

It was my understanding that Blu-Ray drives have two diodes: blue and red. I think it would be a matter of brand and model. I also might perfer a DVD drive for ripping tasks and save the Blu-Ray driver for BD-writing operations.

My own personal experience is the Samsung SH-S162 managed to extract/correct a few discs that my previous drives could not (including several "real"/non-rebadged Plextor drives). That specific model may not exist but a succeeding model should be easy to locate.

Your other chance when you can't get error free rips directly is a ripper (or CUETools) that supports CTDB, which can correct a modest amount of ripping error via a downloadable error-correction code (about 200 kB per CD), provided you ripped the entire CD, not individual tracks.

Your options are CUETools (which includes CUEripper) and the CTDB plugin for Exact Audio Copy (EAC).

The way CDs work, much of the reading is dependent on the servo control to track the focus as the disc surface moves up and down and follow the spiral track accurately and some designs will be more susceptible to losing the track when there are scratches in line with the track. Having a near-infrared or deep red laser in a certain range is likely to be required. I've had different performance in marginal CDs with various drives of the three I own, but really bad CDs are really bad on all three of them.

FYI if you have CDs that are damaged on the play side (NOT the label side) there are machines - often at game sellers - that can repair the discs to new condition. The place I go in Hawthorne CA charges $5 and can fix software CDs as well as audio CDs and do DVDs but cannot do BluRay discs.

This is prolly frowned upon, but the beauty of flac and accuraterip means that you CAN download unrippeable tracks from various sources. In my case I have Led Zeppelin's 'complete studio recordings' boxed set from 1996 or so. All discs are accuraterip except for disc 10, which is Coda with a few extra tracks.  The last two tracks are unrippable no matter what I try as there is a scratch on the disc. The recent remaster of coda does not contain these extra tracks. Thanks to the internet and accuraterip I was able to download those tracks and reconstruct the disc by downloading a torrent of that boxed set in flac accuraterip format.

I had to buy a separate DVD-RW drive because my Blu-Ray player just wasn't happy doing secure ripping on quite a lot of discs. Same discs in the DVD-RW are fine.

The list on dbPoweramp is quite old and doesn't list actual drives, rather what they are named in the device manager so it's quite hard to find them.
