PureRead functionality allows for reproduction of original audio by eliminating Error Data Compensation accompanied by conventional CD Audio play When CD Audio is hit with an unreadable error, the error is filled by a calculation that is formed by data located before and after the error point. These errors are typically caused by finger prints or scratches on the disc. This calculation is made to create an artificial sound with the purpose to create seamless audio listening. PureRead is a unique function that minimizes the Error Data Compensation by judging the disc condition, readjusting the reading method, and then retrying to read the original sound data as much as possible. The function is used to minimize the chance to hear artificial audio. * PureRead function can be set utilizing the Pioneer Drive Utility. Intelligent Operation The drive monitors how it is being used and will adjust its disc rotation speed automatically, meaning it will spin slowly/quietly for audio & movie playback, and quickly for data transfers.
