摘要： A method and apparatus for coherent time-domain optical data storage utilizing a randomizing phase modulation to increase storage capacity. A laser (10) generates write. read, and data pulses which are applied to an acousto-optic modulator (11), which modulates the pulses according to a modulation signal received from a radio-frequency modulator (12), and the modulated pulses are applied to the storage medium (13). The data signal to be recorded on the storage medium is subjected to spread-spectrum modulation, and in particular to pseudo-random phase modulation. The RF-modulator (12) modulates the write and read pulses with a frequency-chirping modulation and modulates the data pulse with the spread-spectrum modulated data signal before applying the respective pulses to the storage medium. The result is that a significantly longer data signal may be effectively recorded on the optical storage medium for a given characteristic de-phasing time of the medium.
