DVD-ROM SL media
The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.
The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks and progresses towards the inner part of the disc.
The specific disc was burned and read back using the Samsung SH-B083L drive. It is obvious that the drive could not read easily read the data around the layer switch area.

The Samsung SH-B083L is a fast drive for your DVD media. It can easily compete other DVD burners and BD ROM drives. However, it had problems reading the DVD-R DL discs.
