Holographic data storage media (10) having a sandwiched construction are described in which a holographic recording material (11) is sandwiched between two substrates (12, 13). The substrates may be formed with fluid containment features (14, 15) in proximity to outer edges of the respective substrates. Also, the substrates may be formed with centerpieces (16, 17) that are recessed relative to outer surfaces of the respective substrates. The fluid containment features (14, 15) may also provide a vent gap (91) through which gas can escape from the cavity when the holographic recording material (11) is injected. Such substrate features can improve and simplify the media fabrication process and may improve media quality. |
