RECORDING DEVICE, REPRODUCTION DEVICE, AND RECORDING/REPRODUCTION DEVICE

摘要

A recording device includes a pulse oscillating laser (11), a half mirror (12) for dividing the pulse oscillation light of the laser (11) into a signal light (2) and a reference light (3), a light shutter (13) arranged in the optical path of the signal light (2), a beam expander (14) for converting the signal light (2) into a light beam of a predetermined diameter, a space modulator (15) for converting the data to be recorded into 2-dimensional image information, a Fourier transform lens (16) for applying the signal light (2) modulated by the space modulator (15) to a recording medium (1), mirrors (17, 18) for applying the reference light (3) at a predetermined angle to the recording medium (1), a system control section (21), a laser deriver (22), a system controller (23), a recording medium drive mechanism (24), a modulator driver (25), a data input section (26a), and a data processing section (27).
