Well, Sony has done it once again… they have released yet another format for us to adopt. Today, Sony Electronics has started shipping Professional Disc for DATA(TM) media that uses blue lasers instead of standard red lasers to write more data onto a disc. This release is aimed at the professional industry first… featuring a huge 23.3GB storage capacity per single-sided disc, Professional Disc for DATA media provides enough storage for data such as medical imaging, broadcast, audio/video editing, graphic design and enterprise content management. The new format will be available in both write-once and rewritable versions with reading speeds of about 11MB/second and 9MB/second write speeds. The discs retail for $45 each.
