16 camadas em um único disco óptico:
Visão obtidas pelos sinais das camadas:
Camada 1 Camada 9 Camada 16
Disco óptico desenvolvido pela Pioneer, possui 400GB, sendo que estão distribuídos em 16 camadas de 25GB cada, o mesmo tamanho de uma camada do Blu-Ray. O fabricante deve lançar
no Simpósio Internacional de Memória Óptica e Armazenamento de Dados Ópticos nesse ano, o evento ocorrerá no Hawaí.

July 7, 2008, Tokyo, Japan – Pioneer Corporation has succeeded in developing a 16-layer
read-only optical disc with a capacity of 400 gigabytes for the first time in the world*1. Its
per-layer capacity is 25 gigabytes, which is the same as that of a Blu-ray Disc (BD). This
multilayer technology will also be applicable to multilayer recordable discs. This
development has bolstered Pioneer’s confidence in the feasibility of a large-capacity optical
disc, which is expected to become necessary in the near future.
For multilayer optical discs, it has been difficult to obtain clear signals from each recording
layer in a stable manner due to crosstalk from adjacent layers and transmission loss.
Utilizing the optical disc production technology that it has developed in the DVD field,
Pioneer solved these problems by, among other things, using a disc structure that can
reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback
high-quality signals from every layer.
As for the read-out system, Pioneer achieved stability in the playback of recorded signals by
employing a wide-range spherical aberration compensator and light-receiving element that
can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism.
Since the optical specifications of the objective lens, such as NA (Numerical Aperture)*2, are
the same as those for the existing BD discs, it is possible to maintain compatibility between
the new 16-layer optical disc and the BD discs.
The 16-layer optical disc technology, capable of storing much more data than the
conventional discs on one disc, will greatly reduce the number of discs to be used and
therefore contribute to the conservation of resources.
Pioneer will present the details of this research at the International Symposium on Optical
Memory and Optical Data Storage 2008 (ISOM/ODS2008 ) to be held in Hawaii from July
13.
Notes
*1: According to Pioneer survey, as of July 7, 2008.
*2: NA: The higher numerical aperture of the objective lens, the smaller diameter of the beam spot focused on a disc surface.

O futuro para mim será discos com maiores capacidade cada vez mais compactados, ou seja, com uma única mídia será possível carregar todo seu sistema operacional, software, documentos e tudo que faz parte do seu PC, tudo rodando a partir de um simples "CD", como já acontece há algum tempo com os Lives-CDs(Linux). Ainda não é possível salvar, editar, excluir arquivos pessoais como músicas, vídeos, como se fosse "Meus documentos" nesse Live-CD. Concluindo, em um futuro não muito distante isso será possível com estudos e mais estudos, pesquisas e mais pesquisas; com certeza esse lançamento da Pioneer abrirá muitas portas nesse ramo para outras fabricantes, como a própria Sony(Blu-Ray). Argumente sobre essa nova tecnologia e o que você acha do futuro.
