Sony will not release further versions of its professional Blu-ray format, the Professional Disc for Data (PDD). According to a report on heise.de, Sony has removed PDD from its roadmap, but will continue to sell PDD drives until the end of 2007. Technical support will be available until 2014, media will be available even longer, the website reported.
PDD cartridge media are able to save 23 GB of data and were developed to compete with Ultra Density Optical (UDO) media. The technology was released in 2004 with the promise to double PDD data transfer speeds with every new generation. Apparently, the PDD was not able to gain enough market share and Sony will market its regular Blu-ray format instead.
