Title:
OPTICAL INFORMATION RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/035633
Kind Code:
A1
Abstract:
An optical information recording device is provided with: a spatial light modulator (101), which converts irradiation light outputted from a light source into a plurality of partial information beams by passing the irradiation light through a plurality of modulation regions; optical mechanisms (102, 103, 104) which collect the partial information beams to a holographic memory recording medium (110) and irradiate the holographic memory recording medium (110) with a reference beam such that the reference beam intersects with the partial information beams on an information recording layer; an actuator (140) which drives the holographic memory recording medium (110); and a control section (130) which drives the holographic memory recording medium (110) and performs information angle-multiplexing recording by outputting irradiation light from the light source with information by switching respective modulation regions.
