From this page and for the following we start our Blu-ray disc tests with the Liteon iHBS112 drive. We remind you that the drive supports 12x BD-R SL and 8x BD-R DL recording with specific media. The discs we used for this test were kindly provided by Mitsubishi Kangaku Media (MKM), the manufacturer of the popular Verbatim branded discs, Moser Baer India, Panasonic and Imation/TDK.

For the first test we used the Verbatim BD-R 25GB certified for 2x burning (VERBATIMw (000)) as well as the brand new Verbatim BD-R 25GB LTH disc for 6x burning. The specific discs have been manufactured using the "Low-To-High" (LTH) process. The LTH write-once BD-R media feature an organic dye recording layer, making them different that the currently available BD-R discs that use inorganic materials.

Notice that not all the Blu-Ray drives can read the LTH BD-R discs. That because the reproduced signal while reading the discs has a LTH (Low to High) polarity. However, latest hardware as well as firmware upgrades to existing players/recorders could add support for LTH recording.

The advantages of the LTH manufacturing technology is that it can be applied without requiring large-scale manufacturing plant investments, allowing for using modified CD-R and DVD-R manufacturing equipment.

It seems that the LiteOn iHBS112 does not support burning of LTH BD-R media. This is an unfortunate issue since these discs are cheaper than the rest BD-Rs and they are expected to be widely available by Verbatim and Taiyo Yuden . On the other hand, the drive managed to read a Verbatim LTH BD-R 2x disc, recorded with another burner. That's a firmware issue Liteon's engineers have to look at.

We also tried to burn the brand new Verbatim BD-R SL LTH for 6x recording with no luck:

The disc was burned in this strange way: In the beginning the drive looked like it would burn it at 6x P-CAV. However, the speed dropped at 4x and soon enough the burning process was terminated at the 4572MB position. We tried to read the disc but we got a read error:
