DVD9

DVD9 is a single-sided dual-layer format DVD disc capable of storing up to 7.95GB of data.

As data is stored within two separate layers, this may cause a noticable pause during playback as the DVD player refocuses the laser to read the second layer.

The main DVD formats currently in use are:

• DVD5 (single-sided single-layer)
• DVD9 (single-sided dual-layer)
• DVD10 (two-sided single-layer)
• DVD14 (two-sided single/dual-layer)
• DVD18 (two-sided dual-layer)
