Pioneer showcases 16-layer 400GB optical disc

Jimmy Hsu, Taipei; Adam Hwang, DIGITIMES [Monday 1 December 2008]

Pioneer is exhibiting its super multi-layer read-only optical disc which features 16 separate layers on a single side with 25GB storage capacity on each layer for a total capacity of 400GB at the IT Month fair taking place in Taipei.

The technology of the super multi-layer read-only disc is based on Blu-ray Disc (BD) with a breakthrough in material of reflective layers, according to Pioneer High Fidelity Taiwan. The specifications of the pick-up head (PUH) of the disc is the same as those for the PUH of blank BD discs, and therefore the Pioneer discs can be read on BD players, the company said.

According to Pioneer's internal roadmap, its super multi-layer technology development is read-only (ROM) discs in 2008-2010, rewritable discs in 2010-2012 and 1TB (1,000GB) disc in 2013, the company indicated.

Holy Jeebuz! But who wants to read that kind of data off of a CD type disc? I mean really.. Is this just for movies? Or are they expecting this to be used in a data application?

BD's aren't that bad for storage if they weren't $30 each.

And one of those discs takes only a day to burn...

Seriously., we're at the practical limit of spinning optical discs. There are physical reasons you can't make the read/burn times much faster than they are already. Time for new technology that gets away from spinning optical media.
