Dynamic Temperature Control makes it easier to produce Blu-ray discs

Krauss-Maffei has developed technology that it said produces optical discs with outstanding moulding clarity and minimal dishing and tilt values, in a short cycle time. The company has developed the patented PowerPulse Dynamic Temperature Control (DTC) system, which is used in the Futuremold III mould series for optical discs. The system can be used to convert existing KM production lines to HD-DVD production, and also makes it easier to produce Blu-ray discs, KM said.

DVD-R 8x discs, produced on KM lines with the overburn function, can be burnt at a high level of quality up to 16x with the new technology, according to the company. The increase in quality is largely thanks to precisely controlled mould temperatures.
