Sony, Pioneer Demo Blue Laser Optical Recorder

The development of a commercial optical disc recording system based on a blue laser is a goal being pursued by many electronics makers at present and is seen as the next generation leap from today's red laser-based systems. Because blue light has a shorter wavelength than red light, 405 nanometers versus 650 nanometers, data can be packed closer together and a standard 12 centimeter optical disc can be made to hold more data.

The system on display at CEATEC this week, named DVR-Blue, is capable of storing up to 22.5GB of data on a 12 centimetre optical disc -- roughly five times the capacity of the latest 4.7GB DVD-RAM disc. The companies said that's enough capacity to record 2.5 hours of high definition television, an application for which they think the new system will first catch on when commercialised.

Sony and Pioneer, which are working together on the research and development, bought a blue laser for the recorder from Nichia Chemical Industries, one of only two companies in Japan that is capable of producing such a device.

Commercial production is, however, some way off. The prototype was such a recent development that few details were available and staff from Pioneer said up until last week they were even unsure whether the prototype would be finished in time.

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

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
