If you continue to have problems after cleaning the disc, you may need to attempt to repair one or more scratches Sometimes even hairline scratches can cause errors if they happen to cover an entire ECC block Examine the disc, keeping in mind that the laser reads from the bottom There are essentially two methods of repairing scratches: (1) fill or coat the scratch with an optical material or (2) polish down the scratch Many commercial products do one or both of these, or you may wish to buy polishing compounds or toothpaste and do it yourself The trick is to polish out the scratch without causing new ones A mess of small polishing scratches can cause more damage than a big scratch As with cleaning, polish only in the radial direction Libraries, rental shops, and other venues that need to clean many discs may want to invest in a commercial polishing machine that can restore a disc to pristine condition, even after an amazing amount of abuse Keep in mind, though, that the data layer on a BD is only onetenth as deep as on a CD and one-sixth of a DVD so the BD cannot be repolished too many times

The storage capacity of a single-layer DVD is seven times higher than that of a CD BD further improves on DVD capacity by reducing the laser spot size with smaller wavelength (26 increase) and a more tightly focused beam (2 increase), resulting in more than five times the capacity At the reference 1 linear velocity of 4917 m/s, Blu-ray discs spin about 14 times faster than DVDs but, because of the higher data density, the data rate is 35965 Mbps, over three times faster than DVD s 1108 Mbps and over 29 times faster than CD s 123 Mbps However, to handle the high data rate requirements of video and audio, discs are played at a minimum of 15 times reference velocity, giving a data rate of 53947 Mbps, about 48 times faster than DVD
