Intersil introduces laser driver for DVD/CD combo
The company Intersil has announced a new dual output laser driver. This laser driver should make it easy for optical storage drive manufacturers to make drives that both read and write CD(-R) and DVD(-R).
Their latest product should make it able to - in the end - write to CD-Rs at 48x, and to DVD-R at 8x. All DVD formats are supported. Here is the technical part of the press release.
This new dual four-channel (one read and three write levels) laser driver provides improved current control to both the CD and DVD laser diodes. Each channel has a separate enable pin for the DVD or CD driver output. This simplifies control and gives 100 percent compatibility with existing single channel designs. The EL6119C incorporates two separate high frequency modulation (HFM) oscillators for up to 500 MHz and 100 mA, peak to peak, per output. The HFMs reduce laser-noise and read-noise error rates. Current outputs of the three write channels are 200 mA, 100 mA, and 100 mA, enabling CD-R speeds up to 32X in compliance with the Orange Specification Standard for CD-R and CD-R/W write strategies and all DVD formats. The EL6119C is part of Intersil's portfolio of write strategy programmable laser driver ICs that provides increased write-speed performance (up to 48X CD and 8X DVD) with increasing integration of system level functions. |
Mind that these are just internal parts of drives and it has nothing to do with acutual drives, but parts like this give us a look at what the future is going to bring (8x DVD writing that is)

The only thing that will make me run out and buy a DVD-R is if I can write 9.4 GB in some form of quazi-dual-layer emulation. Speed doesn't excite me as much.
