"Imagine a vinyl record that has 30% more capacity, 30% greater volume, and double the audio fidelity of a typical LP sold today.
The ‘HD Vinyl’ name is a working title, though the basic idea is this: instead of the manual and time-consuming process currently used for creating vinyl LPs, the ‘HD Vinyl’ process involves 3D-based topographical mapping combined with laser inscription technology to more quickly generate a far superior product. Not only will the end product be vastly improved, but the time required to produce the LPs will also be radically reduced.
The result is a record that looks like the LPs being sold today, and more importantly, plays like them. According to the companies involved, the HD Vinyl disc will play on all currently manufactured turntables, though enhanced features will be better realized on upcoming, HD-compatible turntables."
