Another common writing strategy, used by some 6X BD writers on the market, is Constant Angular Velocity (CAV). This writing strategy starts at a lower speed and gradually speeds up to a maximum of 6X only at the end of the writing session.

Many users don’t use the full capacity of a disc when they make a back-up. “If you use only 75-80% of the disc capacity, a 4X CLV writing strategy will be a quicker solution then a 6X CAV strategy,” says Marketing Manager Jelmer Veldman. “We see a growing market acceptance for Blu-ray as the format of choice for High Definition content playback and for high volume archiving. With this 4X BD writer Lite-On delivers a faster solution for backingup data on Blu-ray Discs.”

BD-RE media can be written at 2X and the DH-4B1S reads BD-ROM discs at 4X. Furthermore, the drive can burn DVD±R at 12 and DVD±R DL at 8X.The maximum speed for writing DVD+RW is 8X, DVD-RW at 6X, CD-R (reading and writing) at 40X and CD-RW at 24X.

The DH-4B1S will be available across Europe at the end of May and complements the Lite-On Blu-ray product portfolio, which also consists of an internal and an external BD-ROM drive.
