TDK Corporation has commenced shipments of mass-production samples of so-called bare-type (i.e., cartridge-less) versions of its BD-R (write-once type) and BD-RE (rewritable type) Blu-ray Discs. The four new products include the BD-R25 (single-side, single-layer, 25GB) and BD-R50 (single-side, dual-layer, 50GB) write-once types and BD-RE25 (single-side, single-layer, 25GB) and BD-RE50 (single-side, dual-layer, 50GB) rewritable types.
Mass production at TDK's Chikumagawa Techno Factory, which specializes in optical discs, will commence upon issue of licensing for the bare disc.
With today's digital society and its burgeoning volume of data, as well as the rapid diffusion of digital high-definition broadcasting, demand has grown for discs that achieve larger capacity and higher-speed recording while at the same time are easy to use. The BD-R and BD-RE introduced by TDK are bare (cartridge-less) discs that fully satisfy these needs for larger capacity and higher-speed recording with high reliability.
In April 2003, TDK had launched sales of the BD-RE120N (rewritable type, enclosed-type cartridge) for recording use. This was followed in November 2004 by the BD-RE135N (rewritable type, open-type cartridge), which received acclaim for its stunning high-definition images.
At the Data Storage Expo in June 2005 and CEATEC in October, TDK unveiled prototypes of cartridge-less, single-sided, single-layer 25GB and dual-layer 50GB Blu-ray Discs, which demonstrated that from the technological standpoint such products had been perfected.
For the Blu-ray Disc, which achieves significantly higher density recording, scratches or dirt can have fatal consequences to the data, so it was initially introduced utilizing a protective cartridge. The BD-R and BD-RE Blu-ray Discs launched this time make use of DURABIS 2, TDK's originally developed hard coating technology. This achieves a recording surface with extremely high resistance to scratches and dirt (particularly fingerprint smudges), thus enabling anxiety-free use of a cartridge-less disc.
For the forming of the cover layer above the disc's recording layer, an original high-precision spin coating is utilized, realizing smoothness at the nano-level while achieving stabilized recording and playback characteristics.
The BD-R write-once type, moreover, makes use of an inorganic material in the recording layer, entirely different from the organic dye used in previous types of write-once type discs. Because the recording layer is not affected by light, it realizes a disc with outstanding archivability. Furthermore, the BD-RE rewritable type utilizes a high-sensitivity phase-change material that realizes stabilized characteristics, in the form of a low error rate, even after 10,000 overwrites.
In addition, the single-sided, dual-layer disc realizing 50GB capacity harnesses high-precision stacking technology resulting from years of work at optical disc development, to achieve precision forming of its respective functioning layers. The upper layer (Layer 1) and lower layer (Layer 0) are combined in terms of high sensitivity and recording layer transparency ratio, realizing stabilized recording and playback characteristics.
The commitment of TDK's advanced optical disc technology has resulted in creation of the world's first 25GB and 50GB high-capacity discs capable of 2X recording speed. TDK is confident that the BD-R and BD-RE, freed from the confines of a cartridge, will offer their large capacities with greater facility, thus greatly expanding the potential of optical recording.
