The drives read and write both single-layer and double-layer DVDs, and they support LightScribe direct disc labeling, including media version 1.2 for high-contrast LightScribe labeling.
The 840-series drives record single-layer DVDs at up to 16X, double-layer DVDs at up to 8X, and DVD-RAM at up to 5X speeds.
LightScribe is a new disc labeling system that gives CDs and DVDs a neat look without ink. With LightScribe you simply burn your data, flip the disc over, and burn a label directly onto your LightScribe CD or DVD. For more info, check www.lightscribe.com.

Both drives are currently available for aproximately 80 euro (HPdvd840i internal) and 109 euro (HPdvd840e external).
