  • Recording apparatus and recording method
    Patent number: 8000205
    Abstract: A recording apparatus for performing recording on a hologram recording medium includes a first light source configured to output first laser light having a first wavelength; a second light source configured to output second laser light having a second wavelength differing from the first wavelength; a recorder configured to perform data recording in units of hologram pages on the data recording layer of the hologram recording medium in such a manner that a recording data sequence is converted into a data pattern in units of hologram pages, the signal light is generated by performing space light modulation on the first laser light on the basis of the data pattern; a reflected light detector configured to irradiate the hologram recording medium with the second laser light; a position controller configured to perform position control; and a recording controller configured to perform control on the recorder.
