Mitsubishi announces new semiconductor laser for 8È DVD-RAM/-R/-RW/+R/+RW drives
Mitsubishi Electric, with the future in mind, released the new ML1XX20 semiconductor red laser with 140 mW output power, capable of 8È DVD-RAM/-R/-RW/+R/+RW recording. In other words, this means a 4.7GB DVD blank can be recorded in 7 minutes! The company believes this speed of DVD recording will become popular already next year.
The main problem for developers will be laser heating. Using new technology, Mitsubishi succeeded in limiting temperature to 75°. In the future Mitsubishi plans to raise laser power to 160-200 mW.
ML1XX20 sample shipments are scheduled to December 2002, volume shipments to June 2003.
