Printable: The top side of the disc has a special white matte coating that allows you to print photos or text on it using a compatible Inkjet printer.
Dual Layer: The disc features two recording layers on the same side, doubling its capacity (e.g., a standard DVD increases from 4.7 GB to 8.5 GB), allowing for the storage of larger files or high-definition movies.
Cake Box: Discs sold in a round, plastic case (spindle) without individual covers for each disc. This is the most economical option per piece, ideal for bulk recording and storage.
