Tohle jsem nasel, jedna se sice o DVD+R, ale je to vicemene to same. Firmware upgrade asi nepujde, nyni se sice pouzivaji stejne mechaniky, ale take specialni media. Pri uvedeni na trh bude potreba upgrade ridici logiky pro podporu beznych medii...
Mr. Driessen of Philips' optical storage:
At this point in time we are demonstrating the feasibility of the double layer 8.5 GB DVD+R technology. We are able today to make a recording on prototype double layer DVD+R media using a prototype writer based on the
current Philips 8x recorder and a single brand of prototype media optimized for the current recorder based on our joint research efforts with MKM (Mitsubishi Chemical Media red.).
The specifications will not be finalized until the end of December 2003 and we will not know how the hardware interacts with new media until such time as it has been manufactured according to the final specification by
multiple vendors.
A firmware upgrade to an 8x drive enabled the prototype drive to record on a specific 8.5 GB DVD+R prototype disc produced by MKM. However, it is likely that new hardware (such as ICs) will be required in the final product to accommodate variations in media and drives from different vendors. At this time, we can say with certainty that 4x, 2.4x and 1x drives lack the requisite laser power to burn a double layer DVD+R disc.
We expect to have a better understanding of this issue once the specification has been finalized and additional manufacturers begin to produce media.
