DVD14

DVD-14 is a two-sided optical disc format in the DVD family. It combines two independently readable sides on a single disc: one side is a DVD-5 capacity layer (approximately 4.7 GB) and the other side is a DVD-9 capacity layer (approximately 8.5 GB), for a total nominal capacity of about 13.2 GB. The format was defined by the DVD Forum and saw use on a limited set of releases in the early 2000s.

Each side of a DVD-14 is single-layer and can carry its own DVD-Video content or other data. Accessing the second side requires flipping the disc over after finishing the content on the first side. Some DVD players can handle automatic side changes, while many require manual flipping by the user. Because it uses two different sides with distinct capacities, the disc is physically two separate read surfaces rather than a continuous single-sided layer.

Usage and market role: DVD-14 was employed for specific releases that sought to separate content across sides, such as main features on one side and extras or alternate content on the other. It never achieved broad popularity and remains a relatively uncommon format, largely superseded by other designs such as DVD-9, DVD-10, and later optical formats. Modern players generally support reading two-sided discs, but the need to flip the disc limits its convenience compared with single-disc alternatives.

Related formats include DVD-5, DVD-9, DVD-10, and DVD-18, which cover other capacity and side configurations within the DVD family.
