Kijanki,
Thanks for the brief and precise technical answer!
Dbphd,
I'm of the same nature as I collect records since I'm 8 and also CDs.
I apply ALL means of careful handling of an art products. Same certainly applies to collectible books, postcards, posters, paintings etc, etc... Some of the records I have placed individually onto the glass frames mint and untouched.
I didn't have large array of CD-players(even given the fact that I also DJ-d), but even with professional CD players such as Technics, Numark the misreads or skips happened even with perfect CDs. I had to mask that skip with effect of the same bpm and than switch to the next song. I didn't reach computer audio DJ-ing, but would certainly prefer it over the CD-player.
In my home audio I had Marantz CD63 that had been replaced with CAL-alpha(?). Both had an ability to misread or skip even perfect CDs for reason or no reason. Using CD with brush or going directly onto the mechanism to clean did only temporary releif.
