A hologram recording apparatus for carrying out holographic recording by
emitting a signal beam and a reference beam onto a holographic recording
medium includes a laser light source configured to output a pulsed laser
beam, a splitter configured to split the laser beam into a signal beam
and a reference beam, a spatial light modulator configured to modulate
the signal beam or both the signal beam and the reference beam, and a
controlling unit configured to control the spatial light modulator to
modulate at least one of the signal beam and the reference beam with a
totally dark pattern for a predetermined period of time, wherein the
predetermined period begins no later than the start of the risetime of a
pulse of a laser beam output from the laser light source.
