TDK's Blu-ray Discs
achieve a high capacity of 25GB on a single-layer and 50GB on a dual-layer at 2x
recording speed and are protected by TDK's DURABIS 2 hard coating
technology
TDK today announces that is has
commenced shipping mass-production samples of its bare-type (cartridge-less)
BD-R (write-once type) and BD-RE (rewritable type) Blu-ray Discs. The four new
products include:
'¢ BD-R25 (write once, single-side,
single-layer, 25GB)
'¢ BD-R50 (write once, single-side,
dual-layer, 50GB)
'¢ BD-RE25 (rewritable,
single-side, single-layer, 25GB)
'¢ BD-RE50 (rewritable,
single-side, dual-layer, 50GB)
To ensure the new discs will be
resistant to scratches and dirt even without external cartridges, they will be
coated with TDK's new DURABIS 2 hard coating. DURABIS 2 technology has been
specifically formulated for Blu-ray Discs.
TDK's Chikumagawa Techno Factory,
which specialises in optical discs, commenced mass production following the
agreement of licensing for the bare disc by the Blu-ray Disc Association (BDA).
The main features of BD-R and
BD-RE Blu-ray Discs include:
1. DURABIS 2 coating provides
significantly greater resistance to scratches and dirt (particularly fingerprint
smudges), ensuring safe use even without a cartridge.
2. Unique high-precision spin
coating creates a supremely flat cover layer, resulting in highly stabilised
recording and playback.
3. The BD-R disc utilises a
recording layer of an inorganic material which is unaffected by exposure to
light, thus offering outstanding archivability.
4. The BD-RE disc utilises a
highly sensitive phase-change dye in the recording layer that realises
stabilised characteristics even after as many as 10,000 rewrites.
5. High-precision stacking
technology precisely overlays disc layers, delivering stabilised characteristics
on both the upper and lower recording layers in a single-sided, dual-layer
(50GB) disc.
