Optical disc authoring, including CD, DVD, and Blu-ray Disc authoring, is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD).
Hitachi-LG Data Storage (HLDS, HL-DT-ST or H-L Data Storage), a joint venture between Hitachi, Ltd. and LG Electronics, is a manufacturer of DVD and Blu-ray optical disc drives [2] for desktop computers and laptops. Founded in late 2000, the company began operation in January 2001. [3] In 2006, HLDS began developing Blu-ray Disc drives. [4]
For Blu-ray discs, 1× speed is defined as 36 megabits per second (Mbit/s), which is equal to 4.5 megabytes per second (MB/s). [7] However, as the minimum required data transfer rate for Blu-ray movie discs is 54 Mbit/s, the minimum speed for a Blu-ray drive intended for commercial movie playback should be 2×. The fastest Blu-ray speed is 16×.
DVD lens supports a different focus for CD or DVD media with same laser. With the newer Blu-ray Disc drives, the laser only has to penetrate 0.1 mm of material. Thus the optical assembly would normally have to have an even greater focus range. In practice, the Blu-ray optical system is separate from the DVD/CD system.
Note: Blu-ray disc recorders can record full high definition videos on BD-Rs and BD-REs. Disadvantages include: [citation needed] Slow initial access/load times due to the optical nature of the disc; Limited rewritability on DVD-RW/+RW discs (typically around 1000). DVD-RAM is better suited for high frequency re-recording (around 100,000 rewrites)
