New technology could make Blu-ray Disc recordable media more affordable
If maximum storage capacity is
demanded of physical optical media, Blu-ray Disc is currently top in that
department. Of course, the high costs of Blu-ray Disc media production make the
format much less accessible than DVD-R, even after the consideration of capacity.
Pioneer and Mitsubishi Chemical
Media are hoping to change that with the development of a lower-cost variation
of recordable Blu-ray Disc. The two companies announced that by using an
organic dye recording layer, disc manufacturing costs would be significantly
reduced.
According to CDRInfo, the technology used in the
lower-cost version is called LTH for "Low to High" recording, which
is included in the Blu-ray Disc Recordable Format 1.2 specifications.
The true savings of this new
recordable Blu-ray Disc come from the manufacturing process, which does not
require large-scale changes in production equipment. The LTH BD-R discs can be
made using modified, but existing CD-R and DVD-R machinery.
Despite the cost benefits, one
hurdle that the new recordable Blu-ray Disc must face is compatibility. Current
Blu-ray Disc drives and standalone players are unable to read the LTH media,
though it may be possible to change that through a firmware updated. Pioneer
may also release new hardware that will ship with LTH BD-R compatibility.
Pioneer and Mitsubishi demonstrated
a 25GB single-layer disc that can be burned at up to 2x speed. LTH BD-R drives
and media could appear as early as spring 2008.
