Abstract: A lacrosse head having at least one of a flexible stringing member and a recessed scoop is provided. In one embodiment, a slot is formed in a head along a stop member, a sidewall, and/or a scoop to provide the flexible stringing member. In another embodiment, the flexible stringing member is a flexible stringing bar that extends from a stop member to a scoop. In another embodiment, the flexible stringing member is more flexible in one direction than another. Through these embodiments, a flexible stringing member can dampen and dynamically narrow the pocket, enhance ball retention, increase pass/shot accuracy, and satisfy pocket-forming preferences. In another embodiment, a scoop has a recess that curves toward a stop member to increase the amount of surface area that contacts a ball when scooping.

Abstract: A method of recording a plurality of holographic images in a holographic media, comprising recording a sequence of multiplexed holograms in a selected storage location in the holographic recording media, each hologram having a respective interbeam angle. The interbeam angle increases for each subsequently recorded hologram to compensate for a variable shrinkage of the holographic media during recording. The multiplexed holograms recorded at the selected storage location are partially or fully overlapped. During reading the recorded holograms, a reference beam is directed at a selected storage location in the holographic recording media at a sequence of incidence angles, each incidence angle being adjusted by a respective adjustment angle. The adjustment angles can be substantially equal.
