For archiving 8K content
We previously used the “angle multiplexing” method that records data by changing the angle of incident light on the medium. We have developed a new“two-dimensional angle multiplexing” method that uses the position of the recording medium as an additional multiplex axis. This method has increased the multiplex number by four times over that of single-angle multiplexing.
We are using holographic memory to record and reproduce compressed 8K video signals. In addition to the parallel signal processing method we previously developed, we have improved the mechanical system, thus enabling a stable reproduction.
We are aiming at establishing a means of archiving 8K video and putting it to practical use as a new recording technology by further increasing the density and data transfer rate.
