According to a news published at Tech-On, Hitachi Maxell demonstrated playback of music data read from HROM, a read-only medium based on the holographic recording technology at its booth at CEATEC Japan 2007.
Developed in collaboration with InPhase Technologies, leader in holographic technologies, the HROM device is still in experimental, and requires more developments (mostly to reduce costs that currently are about several dollars per piece).
This is a good news in my opinion, because means that the development of holographic storage techniques is still alive...
More details about the HROM can be found at Tech-On.
