NEC develops 16X DVD+/-R chip set

NEC Electronics has developed a chip set that will help pave the way towards DVD+/-R drives capable of 16X speed writing.

The chip set consists of an analog signal processor, which is used to control the laser and servo systems of the optical pick-up unit, and a digital signal processor with ATAPI interface.

The two chips are offered in quad flat packages (QFP), which were thinner than conventional chips and better suited for use in the slim drives used in notebook computers, NEC said.

They also consumed 10 per cent less power than their predecessors.

In addition to 16X DVD+/-R, the chip set also supportrf DVD+/-RW formats at 8X, a company spokesperson said.

NEC Electronics said it expected both NEC and Pioneer to use the chips in new rewritable DVD drives.

Volume production would start at the end of June and monthly production of 2 million chip sets per month would be reached at the end of this year, the company said.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
