SafeDisc was a copy protection program for Microsoft Windows applications and games that are distributed on optical disc. Created by Macrovision Corporation, it aimed to hinder unauthorized disc duplication. The program was first introduced in 1998, and was discontinued on March 31, 2009.

SecuROM is a CD/DVD copy protection and digital rights management (DRM) product developed by Sony DADC. It aims to prevent unauthorised copying and reverse engineering of software, primarily commercial computer games running on Microsoft Windows. The method of disc protection in later versions is data position measurement, which may be used in conjunction with online activation DRM.

Spiradisc was a copy protection scheme used by Sierra On-Line on their floppy disk releases for the Apple II. The technique, developed by Mark Duchaineau, involved writing the data on spiralling paths on the disk rather than in concentric circles. Initially, no commercial copying software or bit nibbler could successfully copy the disks it was applied to.

Games which used Spiradisc copy protection include Lunar Leepers, Frogger, Ultima II, Star Maze, Jawbreaker, and Maze Craze Construction Set.

Eventually, Copy II Plus version 5 was able to successfully defeat this copy protection.
