The layer change can exhibit a noticeable pause in some DVD players, up to several seconds. The transfer rates reached by dual-layer media for both reading and recording speeds are still well below those of single-layer media.
Sectors are sequenced from the beginning of the first layer to didc end of the first layer, then the beginning of the second layer to the end of the second layer. In OTP mode, the second layer is read from the outside of the disk.
For DVD-Video a variation of the technique is employed. DVD-Video is always recorded in OTP mode, but the video data is read from the beginning of the first layer dua, the end of the first layer, when this ends not necessarily at the end of the track then reading is transferred to the second layer, but the video data commences from the same physical location that the first layer ends back towards the beginning of the second layer.
This means that the 'start' of the second layer may not have any recorded material present. This is in order to minimise the time that the video player takes to locate and focus on the second layer and thus provide the shortest possible pause in the content as the layer changes. A common misconception is that the disc spins first in one direction, and then another, either for PTP or OTP recording, when in fact DVD-Writers always spin a disc in the clockwise direction.
This results in the video skipping or freezing up for some time as the laser head repositions itself and the system waits to start receiving data again. SL stands for standard single-layer discs, while DL denotes the dual-layer variants.
