Latest Patents
Beazley holds a patent for a "Position feedback system for volume holographic storage media." This innovative method involves holographic recording in a photorefractive medium, allowing for the retrieval of stored holograms with maximum signal-to-noise ratio (SNR). The patent describes a system where multiple servo blocks containing position feedback information are recorded in the crystal, which are made non-erasable through heating. These servo blocks are recorded at specific increments, either angular or frequency, depending on the multiplexing method applied. Each servo block is defined by one of five patterns, enabling data pages to be recorded at positions or wavelengths that facilitate subsequent reconstruction with servo patterns that provide position feedback information. The system also includes components, such as a voice coil motor, that respond to position feedback to adjust the reference beam's angular position, thereby maximizing SNR and improving storage capacity.
