摘要：
The present invention relates to a method for compensating for a wavelength mismatch between a readout reference beam (8') and a recording reference beam (8) in a holographic storage system (1), and to a holographic storage system (1) implementing the method.
According to the invention, the wavelength mismatch (Δλ) is determined (20) and the direction of at least part of the readout reference beam (8') relative to a holographic storage medium (10) is adjusted (22,23) in dependence on the determined wavelength mismatch (Δλ).
The recording wavelength is recorded on the recording medium.
