I’m designing tickets for a school show, and I’m concerned about counterfeit tickets (it’s happened in the past at our school). I’m looking to find holographic cardboard (cardboard that has triangles in it, and every other triangle reflects light). Which I could attach to each legitimate ticket that our art class makes. I’m not worried about the holograms containing actual data in them, I’d just want them to shine so that the ticket-takers know what’s legit and any possible forgers would be scared off. I need it to be as cheap as possible (school budget), and available in bulk if possible. Thanks for any information I receive!

(holograms i’m looking for kind of resemble this image: farm2.static.flickr.com/1240/775287793_eaa32eec0a.jpg?v=0)

Playstation 4 with with HVD(Holographic Versatile Disc)technolog?
sony launch new sony playstation 4 with hvd tech.this is next gen gaming console with very very high and real graphics.the new hvd disk hold storage capacity of 3.9 terabytes (39,000 GB) and a data transfer rate of 1 GB/s, which is at least six times more than the speed of DVD players. This would, without a doubt, become a giant step in revolutionizing the disk storage industry.

Optical Storage
Most optical storage devices, such as a standard CD (Compact Disc), save one bit per pulse. HVDs manage to store 60,000 bits per pulse in the same place, in a truncated cone shape, that has a diameter of 500 micrometers at the top and 200 micrometers at the bottom. The HVD Alliance is trying to improve the storage capacity further to touch its dream 3.9 TB mark by inserting a larger number of cones on each track.

Competing Technologies
In addition to HDV, other proprietary standards are making advances optical disk techno
