We　perform　a　comprehensive　experimental　study　on　holographic　and　thermal-fixing　characteristics　of　Zn:Fe:LilvbO(3).　The　measured　hologram　decay　time　constants,　respectively　caused　by　optical　readout　and　under　dark　condition,　with　thermal　fixing　are　15　times　and　75　times　longer　than　that　obtained　without　thermal　fixing.　This　suggests　that　Zn:Fe:LiNbO3　crystals　are　suitable　for　thermal　fixing.　Multiplexed　recordings　of　300　holograms　using　different　thermal　fixing　schemes　verify　that　a　proper　multiplexing　scheme　such　as　track-division　thermal-lixing　scheme　for　disc-type　holographic　storage　can　effectively　compensate　for　the　negative　effect　of　zinc-doping　on　the　dynamic　range,　thus　the　storage　density　is　enhanced.
