Opposite Track Path
Encyclopedia
Opposite Track Path is a term used in optical DVD
technology, allowing fast switching from layer 0 to layer 1.
A dual-layer DVD with Opposite Track Path means that layer 0 is written in a spiral track starting at the inside of the disc, whereas the layer 1 spiral starts at the outside of the disc. Both tracks are written so that the DVD player will rotate the disc in the same direction. When reading the disc sequentially (as is done during DVD video playback), OTP enables the player to switch from layer 0 to layer 1 without a seek across the entire disc.
