Holographic movies on to a spinner
The first ever movie recording has been made on a holographic disc using technology that allows discs the same size as today's DVDs to store as much as one terabyte of data , 200 times as much as a single layer DVD, and 40 times the speed of a DVD.
Optware Corporation, the developer of Collinear Holographic Data Storage System, has proposed that recording on a hologram disc is the structure that will follow conventional optical discs.
Optware has overcome the problem of diffusion noise read/write, which deteriorates the signal quality, by applying a dichroic mirror layer between the recording and reflective layers.
This prevents the diffusion and allows for an ideal collinear holographic recording. The technology is becoming increasingly known as a high-capacity, quick speed data storage technology for the era of broadband.
Optware has been working hard in developing the collinear holography technique to make holographic recording technology more practical.
It combines a reference laser and signal laser on a single beam, which creates a three-dimensional hologram composed of data fringes.
This is illuminated on the medium using a single objective. This mechanism simplifies the previously complicated systems needed to generate holograms.
Optware also claims that it has also reduced the pickup size, eliminated vibration isolators, has high-level compatibility with DVD and CD discs and obliterates the obstacles that remained in the way of full commercialisation.
