In the groove: holographic vinyl
Holograms have been fabricated in the center of vinyl discs before, but the collaboration between IQ Structures and GZ Media is the first time that they have appeared in the actual grooves that generate sound from a record. IQ Structures says that there is no negative impact on sound quality, and that the technology is now ready for mass production. Photo: IQ Structures.
