A hologram storing device having a reflective mirror for performing translation is provided to move reflective mirrors for an object beam and a reference beam so that data can be recorded/reproduced on/from the inter/outer circumference of a disk without an additional pickup. A reference light reflection mirror and an object light reflection mirror perform translation so that an optical path can be changed. Particularly, the reference light reflection mirror performs the translation upwardly and downwardly and two-axis rotation. The object light reflection mirror performs the translation right and left and the two-axis rotation. Namely, if the object light reflection mirror moves in a right direction, the reference light reflection mirror moves upwardly while the reference light reflection mirror moves downwardly when the object light reflection mirror moves in a left direction.
