I just saw today in the web news of high capacity DVD burners coming soon to market from Sony and Philips.
Sony Electronics says it will be shipping drives in about two months that accept blank DVDs with two data layers. Philips Electronics will start selling a similar drive in Europe in April, but is not saying when it will be available in the United States.
The Sony and Philips drives will use somewhat different discs. Sony calls its variant DVD-R DL. The Philips equivalent is DVD+R DL. Both disc types should be readable in standard DVD drives and players.
Sony will sell an internal drive for $230 and an external one for $330. They will be marketed only for Windows PCs, but the external one should work on Macintosh computers with the proper third-party software.
Philips will sell two internal drives with somewhat different features, both for PCs. U.S. prices have not been set.
The drives will be able to burn regular write-once and rewritable DVDs and CDs as well.
