i wud definitely like blu-ray discs.(much bigger and made by sony). but one feature all discs must have that they become scratch resistant and finger print resistant so that we can use them like pen drives. no need to worry about holding them from the sides. lol do u agree?
The technology is there - TDK offers a very tough protection - but that would mean the media companies would miss out on all those profits from folks having to replace scratched movies.
The TDK Durabis coating is a two coating combination of micro-silica and fluorine in special resins. The micro-silica increases the hardness; the fluorine keeps water and stains out. These coatings are to replace the cartridge that Blu-ray was designed to have. The optical pickup head sits so close to the disc in a "near field" recording format that dust getting between the pickup head and the disc can have crashes analogous to those in hard drives. There is a reason it's called "cutting edge technology: somebody's going to bleed. High definition movies encoded in MPEG-4 could be handled by today's regular DVDs and red lasers (without any additonal features on the disc), but that would mean no royalties for new inventions. Blue lasers are a way to get consumers to pay once again for new equipment, new media, new displays to generate new royalties.
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. 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.>>http://www.supermediastore.com/blue-ray-blu-ray-dvd-media-center.html
