Optical data storage using orthogonal wavelength multiplexed volume holograms [PDF]

open access: yes, 1992
We propose a volume holographic data storage scheme that employs counterpropagating reference and image beams and wavelength multiplexing for page differentation. This method is compared with that based on angular multiplexing. A reduction in holographic

Analysis of beam spot deviation considering vibration of components in optical pickup

open access: yesMechanical Engineering Journal, 2018
An optical disc drive uses an optical pickup to read and write data by focusing a laser beam on the data plane of a rotating disc. The pickup is required to keep the beam spot on the current track.
