	===Note regarding multi-layer discs===		===Note regarding multi-layer discs===
	Dual-layer discs will commonly have ringcode information on ~~both~~ layers. In the majority of circumstances, ~~Layer 0 refers to the~~ inner layer (closest to the centre of the disc) and Layer ~~1 to~~ the ~~outer layer (~~closest to the outer edge of the disc).		Dual and triple-layer discs will commonly have ringcode information on all layers (L0, L1 and L2). In the majority of circumstances, inner layer (closest to the centre of the disc) refers to Layer 0 with Layer 1 and Layer 2 being the ones closest to the outer edge of the disc.

	However, please note that for Sony ~~mastered discs~~, this is often reversed~~, with~~ Layer 0 being the outer and Layer 1 the inner ring. You should carefully check for any identifying information - in the below example (dual-layer DVD), you can see that the mastering code for the outer layer contains "L0", indicating that it is Layer 0 in this case.		However, please note that this is no rule and for many manufactures (such as Sony), this is often reversed. With Layer 0 being the outer and Layer 1 the inner ring. You should carefully check for any identifying information - in the below example (dual-layer DVD), you can see that the mastering code for the outer layer contains "L0", indicating that it is Layer 0 in this case and should go into the L0 field in Redump.

	~~If you are following the [[Disc Dumping Guide (MPF)]]~~ and ~~have a Sony system (e.g. PS2, PS3) selected, then~~ the ~~fields should already be presented to you~~ in ~~the expected order for Sony discs~~.

	If in doubt, please provide a link to a photo or scan of the ring along with your submission to help us process it accurately.		If in doubt, please provide a link to a photo or scan of the ring along with your submission to help us process it accurately.

			===Cinram===

			Cinram mastered discs (IFPI L381 - IFPI L390, most commonly seen on L386 ones) will often have mastering SID's printed as part of the mastering code without IFPI ([https://web.archive.org/web/20260329114458/https://cdn.discordapp.com/attachments/418896419986997249/1487779436215406674/20260329_064205.jpg?ex=69ca6213&is=69c91093&hm=82db3f73accd8fbb56c37998475f519aa7cd738e3f23595af6a21515eea356af& Example]). This is still treated as a Mastering SID for Redump purposes though, so add it to said field and replace it with a TAB character in the mastering code.
