WipeDrive is a long time favorite of mine. It has a seamless installation and setup process. Unsourced material may be challenged and removed.
Without higher rotational speeds, increased read performance may be attainable by simultaneously reading more than one point of a data groove,  but drives with such mechanisms are more expensive, less compatible, and very uncommon. Copy protection Introduced inMacrovision is a system that reduces the quality of recordings made from commercial video tapes, DVDs and pay-per-view broadcasts by adding random peaks of luminance to the video signal during vertical blanking.
Sending OPC calibrates the device laser power at the beginning of burning session to adjust the properties of each recordable disc. This results in a faint rainbow-like noise at and briefly after the point of the cut as the old video recording missed by the fixed erase head is never completely erased as the new recording is printed.
