So, how can one read the data from any area on the disc? The data on the optical disc is encoded as a series of small cavities called pits, that are organized in a spiral called a track. It is the drive embedded software (firmware) that “plays police” - decides what area of the disc can be accessed and on what conditions. The drive itself can easily read all the data technically. In the end, any regular optical disc drive has a complex set of rules that dictate what areas of the disc can be accessed on on what conditions. This data partitioning was further “enhanced” for blu-ray. A drive locked for Europe would not allow reading the data from the disc that was locked for South East Asia, where exactly same disc could be bought at a cheaper price. This was part of so-called CSS protection and was used both for rights management and to enforce disc region price fixing. However in order to read the data from another area of the disc, the software had to know a certain secret key. The disc was divided into two areas - one area could be read as usual. Things changed for DVD, with the CSS protection scheme.
Many data formats were invented at the time (sector mode 2, p/q channels, sub-channel-data,etc), but in the end it was all about positioning the laser pickup head, scanning the disc, and handling these data over for processing. Back in time when CD was invented, the optical drive was just that - device that scanned disc surface and passed this data to PC. What is an optical disc drive? It is a device that scans the surface of a disc with a laser and passes this information to a controlling software on a PC. Please read below the overview of LibreDrive architecture. LibreDrive compatible drive is required to read UHD discs. A LibreDrive would never refuse to read the data from the disc or declare itself “revoked”. Seems like a pretty solid endorsement of the drive's capabilities if that software is bundled by the manufacturer.A LibreDrive is a mode of operation of an optical disc drive (DVD, Blu-ray or UHD) when the data on the disc are accessed directly, without any restrictions or transformations enforced by drive firmware. Power2Go® 8 gives you the ability to burn your valuable files to Blu-ray (including triple and quad layer BDXL discs), DVD or CD media. PowerDirector® 15 LE allows you to import your home movies, edit them, and then upload them to social media sites. PowerDVD™14 delivers award winning playback software and will even upscale standard-definition content to high-definition quality. () Product key for free download is included. It is needed to be downloaded through the WEB. The BDR-XD07UHD includes CyberLink Software, “CyberLink Media Suite 10” only for Windows OS.
