Abstract:
An optical recording apparatus comprises: a focusing section that focuses to a transmission type recording medium a recording light beam including a signal light beam and a reference light beam which are radiated from a same direction with a common optical axis; and a focused-position moving section that moves with respect to a direction of the optical axis a focused position where the recording light beam is focused to the transmission type recording medium by the focusing section, wherein an interference fringe formed by the recording light beam is recorded in the transmission type recording medium at each position which is moved by the focused-position moving section.
