Provided are a holographic recording medium, a method for adding address information to the holographic recording medium, and a method for addressing that can identify two-dimensional information pages by a simple addressing operation. In the holographic recording medium 12 , two-dimensional information pages 40 A, . . . each comprising multiple pixels are multiplexed and holographically recorded. A plurality of pixels in each of the two-dimensional information pages 40 A, . . . form address pixels, and a set of the address pixels form an address information region 42 A, . . . . The address information region 42 A, . . . is disposed at a different position in the two-dimensional information page 40 A, . . . on a two-dimensional information page basis or on a page group basis comprising a plurality of two-dimensional information pages.
