TDK has announced that it has reached a licensing agreement with Sony to begin producing the TDK Professional Disc, a rewritable optical disc compatible with Sony's Professional Disc System. The TDK Professional Disc uses a blue-violet laser with a short wavelength for recording up to 23.3 GB of data on a CD-sized optical disc. That's about five times the capacity of a DVD. The new media should be available in June.
