Ring based Protection with multiple (12-22) rings. Standard dumping methods apply as per http://wiki.redump.org/index.php?title=Ringed_Disc_Dumping_Guide.
Rings exist in multiple configurations and can be found either at the start or end of disc depending on version. Sometimes they will also have single ring sectors (Actually an EDC error) in between the actual rings like in http://redump.org/disc/113120/.

Some Laserlock discs might not rely on traditional ring sectors (example) in favor of a bad sector scheme that most closely resembles Ringed CopyLok. These should be dumped using normal dumping methods using a Kreon flashed TS-H353B/SH-D163B until more research is done.
Laserlock Patterns
Unlike many other ring based protections there is a rough method to tell exactly how large each ring is.
Using http://redump.org/disc/30979/ as an example.
- 2099-2176
- 2474-2551
- 2849-2926
- 3224-3301
- 3599-3676
- 3974-4051
- 4274-4351
- 4574-4651
- 4874-4951
- 5174-5251
- 5549-5626
- 6224-6301
Notice how each ring starts on either a 4 or 9 and ends on either a 6 or 1. This is known as a Laserlock pattern and is believed to be an artefact of the mastering process for these discs. Finding it using our current dumping methods takes a lot of time though. And it is currently not something we ask of dumpers.
