Abstract

In order to provide a more practical, thin and lightweight hologram medium cartridge, a cartridge case is provided with a hologram accommodating recess for accommodating a holographic recording material, the holographic recording material is accommodated in the recess, and a surface of the holographic recording material accommodated in the recess is covered with a transparent substrate.

Description

technical field [0001] The invention relates to a holographic media box, in particular to an accommodating structure of a holographic box into a housing. Background technique [0002] In recent years, compared with optical discs such as CDs or DVDs, the recording capacity of information is particularly high, and it is not necessary to rotate the media at high speed, which can omit or simplify the media drive system of the recording and playback device. Therefore, as an information recording carrier, holograms are used. holographic media has received attention. [0003] A holographic medium basically has a structure in which a holographic recording layer is sandwiched between two substrates. Moreover, in order to prevent deterioration of the holographic recording layer caused by exposure, a technique of housing a holographic medium in a light-shielding case has been proposed before (for example, refer to Patent Document 1 - Japanese Patent Application Laid-Open No. 2003-3174...
