In the spirit of continuous improvement, Sony Corporation announced
on Thursday a new design of the blue-violet laser unit that measures just 3mm
thick. The laser unit is a crucial component of Blu-ray Disc drives and
players.
Developed in part with Nichia Corporation, the new
blue-violet laser is now small enough for practical integration of Blu-ray Disc
playback and record functions into mobile applications, such as laptop
computers and in-car entertainment systems. Sony said that its less-than 3mm
thick laser unit will enable Blu-ray Disc drives measuring in 9.5mm thickness.
Besides improvement in packaging, the new laser unit also
features more stable reading of dual-layer media and new reading capabilities,
such as the ability to read organic media.
The shrink to a 3mm design also cuts down cost – a critical
point in Blu-ray Disc hardware. Last year, Blu-ray Disc movie players hit sub-$300
levels. Analysts now believe that it costs Sony around $400
to manufacture each PlayStation 3, thanks in part to the falling costs of Blu-ray
Disc drive hardware.
With the falling price of Blu-ray Disc assemblies and processor
die-shrinks to 65nm, SCEI chief
Kazuo Hirai expects the PlayStation division to be profitable
starting next fiscal year.
